Well thanks for your replies again. I suspected an air leak, and have gradually been taking apart the saw. Eventually I found a ruptured impulse seal which I think may be the culprit. Genuine part only though £10 for a small tube the size of an earser that you find on the end of a pencil! I have written up my finding here is any is interested.

Wow. Thanks for all of the tips guys. I really appreciate it. The chain will stop by riching up the low jet, but pretty soon after the saw stalls. I have changed the clutch assembly, and replaced the sprocket (and bearings) without it rectifying this problem. I have also used a torch to look inside the carb, and can see that the round flap fits snugly in the aperture. I would also say this problem has been getting steadily worse over around 2 years of occasional use. Really happy with response. Great forum

So is this air leaking in to the combustion side of the carb, or a worn (?) piston or something. I have purchased a replacement saw ( a husq 545) but I would like to repair this is possible. Thanks for your reply.

I have a 10 year old husqvarna 136 which I have owned for 3 years and done 2 seasons worth of firewood. The chain turns when the saw idles, I used to put on the chain break but now it revs so high the chain break will not hold it. I have changed the diaphragms and other soft parts in the carb, and I have adjusted the idle screw ALL the way out, the low jet is set the the point where the saw chokes and dies, but yet the chain still moves at idle. I have also tighten the clutch spring, but the saw is obviously revving way higher than it should so I do not think it is a clutch problem. I would appreciate any pointers.
