Fave chainsaw played up t'other day - had been using for an hour or two -
all as normal - then starting dying when should have been idling - i.e.
make
a cut release throttle trigger, and revs drop down and .....conk.

Would restart -on full throttle - and OK at revs but conked again when
returning to idle.

Next day the fecka won;t start at all.

Had plug out, bit sooty but cleaned up OK, magneto creating a spark -
felt
through fingers from plug lead, quite hard to see spark on plug tho??

Fuel OK (other backup saw running well on it), after trying to start
(again)
plug/cylinder is wet so presume fuel getting there.....

Has a decompression system to start and is hard to pull without using it
so
assuming compression OK.....

Will get a new plug - anything else?

Recently it was stored on it's side overnight due to persistent chain oil
leak - could this be related?

TIA

Air filter blocked?

well it ran at high revs until it failed so assuming air and fuel was/is
not an issue... plus the air "filter" is only a fine gauze screen that
looked in a reasonable state (has been worse w'out this issue)

I have one doing exactly the same.

It is one given to me which would not start

Cleaned all up stripped carb checked diaphram etc new fuel etc got it to run
fine for about 30 seconds then old fuel pipe gave way

Replaced fuel pipe with a proper one from garden machinery repair shop
(rather a than the piece of aquarium air hose I had in stock)

Was still a b****r to start not helped by starting instructions being in
swedish

when I did get it to run it ran for 30 seconds and whilst on almost full
throttle cut out and would not restart

both my other 2 stroke tools start fine so it is not that I cannot do 2
stroke

If you do solve the problem I would love to know

Regards

2- strokes quite frequently suffer blocked exhausts too. Look for signs
of smoke escaping slowly.
