So were back in business, electrics all sorted and made a few upgrades too. got the little McCulloch sorted, and got a McCuloch Pro Mac 6 and that's now running too. the 350 Husqvarna that I was not particularly impressed with has been rebuilt and I have to say as given some decent reports here has been given a second chance,, I have to say it's a lively little thing, and very light and well balanced. and I picked up an Alpina 70, and there's a Poulan on it's way to me soon. I may have to build more shelves.

any ideas tw230 loads of black smoke wont turn of on key changed pump solenoid no difference thanks all

today's effort

Thats looks like a decent chunk of metal that caused the problem. So im thinking no to piston ring pins and circlips. I am thinking that part of a main bearing has broken away but if you have pulled the crank seals and ruled that out then all I can think of is a foreign object like a screwdriver to maybe lock the piston to remove the clutch! Or maybe some baffles in the exhaust have broken loose and ended up in the cylinder.

Interesting. What's so different? The injector bolts on and off like a carb. Is there a separate air inlet? Any sensors on the exhaust side?

I will be interesting to see the Husky fuel injected saw, I cant get hold of the parts list to compare it the the 500i. The 500i is built completely different to standard non injected saws and it is more of a PITA to strip down. Ive rebuilt a couple of them and you need to strip them to bits just to replace the piston and cylinder.

Thats the problem. HSE overacts and the pro sector has to pay for it. Meanwhile the domestic sector can more or less do and buy whatever they want due to the likes of lidl/aldi and ebay. One of the best over reactions I had dealings with was someone working on network rail decided to put his hand in the gob while felling a tree and lost quite a few fingers. The reaction was to make it a requirement that all chainsaw operators ware chainsaw gloves. Im sure that that really cut down on accidents.

It should be 3.5mm on the 372. As a very rough guide 50-90cc 261/550 - 462/572 use 3.5mm, 90+ 661/395 use 4mm for Husqvarna and 4.5mm for Stihl. Small top handles and machines with easy start use 2.7/2.8mm, small saws and regular top handles use 3mm. The average length of the cord is 800mm but this can go up to 1000mm for blowers and brush cutters. Its always worth having some 3.5mm cord in the van as this will fit most machines and can sort out the bigger machines for a quick fix although you may not manage to get it to fit through the starter handle or pulley on the smaller machines. Its always worth changing starter cord once a year as if it does go out in the field it can be clips, springs and recoil springs flying in all directions and a lot of cursing. To give it a quick check pull the starter handle out then pull the handle down the cord and check the cord where it goes into the bottom of the handle as that is the most common place for it to wear. If you have the starter cover off check the cord at the point just after the stopper knot in the starter drum. We sell cord by the metre so you dont have to buy 30 feet of cord at a time.

Codswallop... you fishing for puns again?

There's got to be something wrong with it up the business chain because the saws are great. Remember when the car makers were worried about microchip supplies?

Stihl made concrete saws with fuel injection for a while before they tried it with chainsaws.

The sections that have narrowed are where they pass through the muscle wall so not suitable to stent. I’m now stuck here for at least another two days while they check the medication is doing it’s job

Cant advice for you, only you know. I know a arbor guy over 70 years old. He is not you, and i doubt my friend would ask for advice if he can or not do it. you either do it or you don't. you wont beat a 20 year old confident guy, your only road is being your own boss. You won't be able to get the experience i have, from starting from age 12, you starting at age 50 or so, the only thing you need to focus on is understanding the tools not killing yourself. First thing i would work on is confidence, and go from there.

Let us know how it goes, refurbishing the carb is always a good idea but don't ignore looking at the condition of the piston as it may have slightly seized causing your issues.

Hi all Just wanted to let guys know running a predator 38 the difference in changing the pulley from 200mm to 225 mm. The difference was remarkable, quicker recovery time when rev goes down, and better torque, had to do some cutting here and there to fit it. but was well worth it. Less bogging down and faster grinding, specially deeper down.

With respect, Mr Stubby, that's codswallop!

What's the deal with the arteries being in the wrong place? I hope all goes well.
