Go back to eBay and the police....chances are they will do cock all but you never know. You can't judge the whole company by one rogue employee but I would be bloody enraged over that!!

I have used DHL and ParcelForce. I book through a broker rather than direct as it is a bit cheaper. Depends on if you are dropping the parcel off or getting it picked up. ParcelForce are probably the better of the two but the Pandemic and fuel issues helps no one. Make sure the saw is drained - both tanks. Ensure no smell of fuel - leaving the fuel cap off overnight and then refitting helps. Make sure the saw is bagged to keep any stray fluid and smells at bay. Make sure the dogs/spikes, if fitted are sufficiently protected from piercing the box and if a bar is sent, they tend to eat their way through the outer box so put a cardboard cap on each end and make sure nothing is moving in the box. If packed correctly, the box can be dropped at waist height with no damage to the contents.

Used vegetable oil for bar oil?
spudulike replied to nemcc's topic in Forestry and Woodland management
Any oil that dries over time shouldn't be used in a chainsaw. Seen it too many times before and after trying all types of cleaner and resorting to craft knives to carve it off, now I just leave it in place and if a customer wants to wreck his saws then that is fine by me!!! -
I would say that all modern machines have "automatic oilers".....that is they oil only when the chain is spinning taking the drive from the clutch drum. Oilers that run all the time...like on early Stihl 024s were more common in the 70s and 80s and ones with manual pumps you actuate with a pumping action more common on much earlier saws and the 70-80s biggest saws used for felling/milling to assist the longest bars. It is most likely the saw oils only when the chain is spinning. Some lower cost saws have a fixed oiler and the more semi to full pro saws have adjustable oilers. Check the oiler hole in the bar and ensure it is clear. Check the oiling Chanel is free of chip, put the cover back on and adjust the chain tension......the way to check the oiler is to point the bar bottom tip at a clean surface, piece of wood etc and rev the saw hard. You should see a line of oil form within a few seconds. It will take a little longer if the oil tank has been emptied but no more than 15 seconds.

Google is crap!! Can't match this one up
spudulike replied to MrMad1966's topic in Tree Identification pictures
Strange that but from the shape of the twigs and the bud shape, I thought exactly the same...Magnolia - we have two in the garden......that is from the top three photos. The bark is pretty smooth, bit like young Ash if it is. -
Yup, L&S...they purchase direct from the manufacturer so can usually advise if there will be any supply issues. Usually good for most manufacturer types apart from Echo.

You can use a brake bleeder kit to produce a vacuum, a bicycle pump for pressure and use a Gunson low gauge as I did for a bit but the Mityvac does it all for you but obviously at a cost and there is the rub. I have used mine a few hundred times and it has saved me loads of hassle finding issues and ensuring my customers get a saw that is perfect and won't go pop in the next few years. In your position, you are likely to use it once or twice and that is the issue, someone running a business needs this sort of kit and can invest in it amortising the cost over many repairs and unfortunately, you can't unless you enjoy this sort of work and start your own business etc etc...... Maybe a simpler method is the saw should die if you turn the L screw all the way in, if it doesn't, it most likely has an air leak.....it takes a bit of experience but is an indication!

Not done the oil pickup on an 038 before but from what I can see, you push the rubber pickup on to the metal elbow that goes through the oil tank wall. Generally pickups push through from the clutch side oil tank wall but this one looks like two flexible hoses go either side of the solid elbow. try it, forceps are generally a good tool for this sort of thing. If the hose is OK, leave it well alone!

The suspense is climbing...not much to live up to after 12 pages of posts

Piston back on..make sure it is the correct way round - arrow to the exhaust port and make sure the circlips are 100% located - gaps to the top on Stihls. Sometimes the base gasket needs fitting prior to fitting the piston. Fit the manifold to the cylinder and then refit the cylinder and pull the manifold through the air box back plate. A nice smooth pair of long nose pliers work for me NOT a sharp screwdriver....seen the result of that too often.
-
Yup, they do slap a bit when old and worn, I have had a couple that have slapped so hard, the skirt has shattered - just what they do and guess the piston and bore design just allows it with high use! The pic Wonky put up with the paper in the bore is one of those, so much slap the piston skirt has shattered! Sort of shows my "Wobble Check" for piston wear as well.
-
I wasn't commenting on your answer or opinions and more on what I do and have found in my experience and was answering the OPs question. We all have our ways ...no offence......but have found a new Meteor or Hyway piston is often not really much more costly than a set of OEM piston rings so go that route. I usually take the rings off, push the piston up the bore, stick my finger over the plug hole and see how easy it is to pump up and down. I then put the piston so its base is close to the open end of the cylinder and see how much clearance there is from the skirts to cylinder by pushing it back and forth across the bore with my thumbs. Very subjective but after you have done a few....it works for me. Comparing new against old is the best way but isn't often able to be done. Ring wear is measurable and if the ring is done...the piston is likely to be the same.
-
On fitting a piston v new rings....If you fit new rings on a worn piston, you will possibly get good compression after 6 pulls BUT...the first pull should give at least 70psi and the new rings on their own will just not give the same compression and will be VERY noticeable when the saw is hot. This is difficult to explain but I had an 024 pulling 180 psi once but the piston was very worn and it barely had the power to pull the chain round and hot, it was pathetic. The piston by itself with no rings causes an initial compression (not enough for combustion) and the rings then up that and create a seal good enough for combustion. The seal of the piston to the bore is just as important as the rings in my experience. Lastly, the piston skirts seal the inlet and exhaust port at different parts of the two stroke cycle. If the piston is worn, you will get FREEPORTING which is where the crankcase pressure or vacuum is lost out of a port when the piston should be sealing it. If your saw puffs heavy vapour out of the back end of the carb when revving it up...it is freeporting!! That is bad!! Just fit a new piston...do the job once and correctly!

The breather pipe is usually clear and usually have two very coarse grub screws in them to stop fuel pissing out but allow air in. Check and you will need pipe of similar internal bore and the screws will need to be reinserted. On the gasket, remove as much as possible and I use a very sharp wood-chisel to remove the residue - obviously at a very flat angle to the surface like you are taking off a very fine layer of wood and not at a vertical angle using a mallet
-
I usually use eBay for non OEM parts but there isn't much available out there. Not sure what you are going to have to do....trouble with old saws!
-
That is one of those issues that is best diagnosed in front of you. Difficult to see if it is the clamp the control shaft pushes in to is worn or if something else is broken or the retaining/earth spring is deformed.
-
The impulse line looks like a length of fuel line that L&S sell in Meyer lengths so just purchase 1m and cut to length. Remove the carb and boot support ring and the boot can be pushed through the air box back and withdrawn from the tank moulding and will then come off with the cylinder and is held on with a metal clamp. The AV mounts...best replace them ..not sure about the other stuff you mention about them ..worth looking at the parts list and seeing what the bits you talk about are shot or not. If the rubber disks are the bits on the front tank mount, they look OK but worth fitting new if perished. They are buffers! The crank looks OK, no pitting that I can see so OK despite the colour. You have inspected the big end cage....the bit you rotated with the pointy thing....good thing to do if you have big scores in the bore. Just clean, inspect and replace what is shot. The carb will obviously need removing and check for type.
-
As above, go around the bore as if you abrade up and down in one area, you can create a slight cavity in the bore and get issues with blowby past the ring. Just do it lightly and let the chemical do the heavy lifting.
-
Sounds good to me...crack on....
-
Right...use battery acid, brick cleaner or a strong alkaline solution to eat the aluminium transfer away. Start with around 180 grit once the acid/alkaline has done its job and then try more chemical as it will oxidise the transfer surface and then you take off the surface to let the chemical work again. Once the bore is pretty clean, roughen up the surface with the wet and dry so the new piston beds in...the 180 or a bit finer will do the job but don't go mad with it. Fit a new piston, OEM Stihl, Meteor and Hyway are best and them Golf and VEC who I suspect are the same Indian manufacturer or take your chances with a no brand type. No need to remove the tank, just remove the cylinder, the inlet manifold bellows should come off with the cylinder and the impulse should be easy to remove and inspect once the cylinder is off. Motomix....fit a new carb kit- I think Stihl used Bing carbs on some models and either Zama or Walbro on later units so ensure you identify carb type before ordering the kit. Rowena are very good but may not take a single order. A new fuel line and filter would make a lot of sense. When it is working again, tune the carb to run rich to protect the saw and avoid any issues
-
The intake damage on the piston is often when the build up of transfer on the exhaust side pushes the piston backward and against the inlet port side causing a mini seize. A bad bearing is more likely to scuff the sides of the piston. If the machine is going to get some serious use, you want to learn a bit and are a bit masochistic, fill your boots, otherwise, just check for play like I said. You could pull the clutch side seal to check the cage further but up to you and your ambitions. Splitting and rebuilding a saw is generally a bit beyond most unless you have been around engines a good time.
-
I would check the main bearings for play by moving the crank end and flywheel up and down, forward and back and if you can feel no play then carry on I say this as to do the bearing work will require splitters and a 10" G clamp and a good engineering background. There is much that can go wrong and if the bottom end is sound, leave it well alone. Cleaning - I use white spirit, cheap paint brushes and a compressor. The cylinder looks reasonable. Rub those streaks of transfer with wet and dry, apply acid or strong alkali, when it stops bubbling, clean and rub a little more and repeat until no bubbling is present. You then need to rub the cylinder to roughen the bore and so you can't feel any high points on the cylinder surface. A hone does this and is what I use but you can get by with just abrasive paper. How were the manifold and impulse? If you have no pressure/vacuum pump, check the rubber parts and tune the carb a bit rich to ensure the repair lasts.

Mark is correct on the settings. I have no idea what limiters you removed as I have never seen any. All the saws I have seen have D shaped H&L screw, the early had a Phillips idle screw and the others, a D shaped idle screw. Reset to Marks settings, adjust the idle and it should run OK.

Smear over the whole surface.

Yes, simple mod, just seal the mating faces with a suitable liquid gasket.
