OT: chainsaw question

It's got a petrol engine in it, so somebody here may be able to help ... Husqvarna 36 starting problem ----------------------------- Same problem since new (in 2005) but getting worse. From cold, pull choke, pull starter MANY (20-50) times. Eventually it fires, runs for a few seconds, dies. Next step is to close choke and pull starter many more times, hopefully to clear the flooding. After 20 or 30 pulls of starter, pull choke about half way. Pull starter some more. Engine probably starts. If left to itself it will fast idle for a few seconds, then die. If I open the throttle - either gently or immediately to fully open - it revs a little then dies. Repeat as necessary to clear possible flooding. Try again with a little choke. If I repeatedly open and close the throttle as fast as I can it will try to rev every time, and if I'm lucky after several squeezes of the throttle it revs properly and will get to full speed with the throttle open. By this stage I can use it to cut wood. In between cuts it will tick over perfectly. If stopped and I try to restart it within a minute or so, it starts OK. If left to cool, it usually is just as difficult to start. Sometimes it's more successful if the choke is pulled only half way. Hasn't been used since last winter. This autumn, after it's fired and died, I take out the plug and burn off the fuel with a blowtorch, warming it up. Re-fit, try again - starts and dies. Checked the spark - it uses a simple magneto - nothing unless the starter is pulled quite fast. So I've replaced the coil - no better. Any ideas, please?

Decompressor in if applicable. Saw on ground, right heel on rear handle chain guard, left hand on front handle with arm straight. Sharp pulls with right hand.

It's interesting watching your daughter start chainsaws, blowers, hedge trimmers, pole saws, stump grinders and chippers, 2/ and 4/ and in all weathers and in a way that suggests 'it *is* going to start'. ;-)

Mind you, it was just the same with her PW50, TY80 and ETZ250 (but with her foot and not her hand). ;-)

Cheers, T i m

p.s. I was probably no more than 10mm away from her giving me a good punch in the face the other day. 'Dad, best you don't stand behind me when I'm starting stuff ...' ;-)

I agree. I've just replaced my old electric one for another electric one - just under £50 from Screwfix.
