You should be able to depress the primer bulb with thumb pressure and there should be some fuel in the primer bulb in around 5-10 pushes. Thumb pressure - around 1/3rd of the total thumb pressure you can muster! It isn't difficult!

I think the crank bearings or stuffers are the most likely cause. Have you tried it without the clutch and drum being fitted as the clutch can rattle. You can try to turn the engine over slowly with the plug out and see if there is any resistance or tight spots.

You are welcome, I was pinching your ideas and revamping them for my own gains - I think they call it plagiarism. Any ideas on Brexit Sorry, just skimmed through the post without really taking in details of whom said what. I can't see what your emoji is on my browser - was it the finger

He shoots, he scores, blah blah

The low speed adjustment controls the mix from idle up to around 6,000rpm and then the H speed takes over. If the saw is pretty boggy from idle to mid revs, the L speed adjustment should help if there is no issue with the saw apart from this.

The saw will change its characteristics once it is run in and it will make more compression and have more power but you will probably find if you rich up the L screw, the saw will benefit from it.

Following on from ADW, the ripped out seal would cause a big air leak and would stop the crankcase making vacuum (when the piston goes upwards) that is needed to pull the fuel and air in to the bottom end.

At my age, you tend to have got pretty much all you need and just purchase what you don't so my wife gets me a lot of "silly" personalised items of food, toiletries, car stuff whilst I try to get her something that she may like but not stupidly expensive. It works for us!

There is a test for the pump on the software and PC interface but not too much help here - they are usually relatively reliable though. The purge bubble should get fuel in it when it has done its job. It basically hauls fuel through the normal fuel line, through the carb and back in to tank. If the saw has lost most of its compression or has a major air leak, it can stop the engine pulling fuel through but is unlikely on a 2 year old saw. These autotunes don't tend to pull loads of fuel through and the plugs don't tend to look that wet even when choke is used many times. If you are brave, you need to pull the carb off, make sure the fuel line pisses out fuel, then remove the pump cover and check the pump diaphragm, the gauze strainer and that there is fuel in that section. Do the same for the metering section and you will hopefully find where the issue is. These machines should fire if petrol is put in the plug hole unless the coil is shot - seen one like that! Most likely issue is shyte in the gauze strainer! .......when I say shyte, I mean wood chip not....you know what

nope innocent, just getting through the cleaning cycle without showing the "check water" error would have been good. Strange arrangement inside but got it sorted before midnight! Porting....that could be interesting.

Bloody dishwasher packed up around 9.00pm Christmas Eve...bloody Germans, it is only 10 years old. Up late and got the fecker going thanks to a bit of Youtube and common sense. Not the ideal Christmas Eve but enjoyed the carols from Kings. Now feeling a bit jaded after a big dinner and a 6 mile walk....did get a slight nap around 4.00

Happy Christmas to all, thanks Mr B for the forum and its following.

Yup, even you, always a good laugh, even the wife knows your name be scared!

Well, on the Eve of Christmas, I would like to wish all my customers a very Happy Christmas and a healthy and safe New Year. Thanks for the custom, hope it has been a happy, productive and good experience and long may it continue - see you in 2019.

Yup, water based and add to deionised water. The solvent based ones are likely to be a big fire hazard.

I think the will to fix it is what is needed, with the will, you have the inclination to learn how to diagnose, to repair and to learn more. Just plonking an hourly paid guy on a course isn't going to give the best result as he can just sit there and let it wash over and if he can't fix something, a colleague can sell a new bit of kit to the customer. With what I do, if the item is not fixable I haven't got a backstop.....oh feck, now sounding like a bloody politician!

You should see some of the uneconomical repair saws I have had in......damn, they are still out there working One came in a box of bits....strange thing is, all I did was rebuild it as I didn't find too much wrong with it and it is still running over a year later - couldn't understand that one Guess the dealer got inside it, got confused at all the bits and gave them back. I did hear from a customer that his local agent told him his piston ring had broken and showed him the gap in it. The customer told him that the ring should look like that, the gap allows the ring to go on and off the piston and closes up once on the cylinder......WTF

Yup and a heck of a lot of compression!

They are a bit, was using my 357 the other day, had a lot done to it and it is mad fast.

If you are thinking about cleaning bio oil off cylinders, forget it. Best get a 1-2 litre heated tank with about 100w. Useful for cleaning carbs but little else to do with chainsaws. I have had clock movements in mine. The little ones are OK for jewellery but would get a better one if you are using it for saws. Simple test is to see if the US will blow holes in thin foil.

I like No 5, cut a suitable perch to sit on whilst cutting off another bit.

We light ours around 4.00 and keep it going to bed time. If Christmas is cold then it will get lit first thing, love the log burner, only small but works really well, lovely heat, nothing like it. Got around 3 years of wood out the front but it needs cutting up.....anyone have a chainsaw

Finished off another two MS200Ts today and then ported a 372 that had gone pop after repair by A N Other. All tests were good but bounced off the rev limiter when flat out so wound it down to under 13,000rpm to keep it safe especially after fitting a new piston. Should pull like a train once it has been run in a little.

Ding dong!

Unfortunately there are a lot of "special" people in villages and some need to be reminded that the countryside has been around a lot longer then them! They seem to come out of well paid London jobs and don't quite understand why all the serfs the village shouldn't doff their caps to them.
