Stihl 010AV Chainsaw Running Issues

[candor]

Hi all,

I have been tinkering with my grandads old chainsaw (Stihl 010AV), got it running this evening finally. Now when I go to rev her, she wants to die, seems to be idling fine though. She did rev up for a while before but then wouldn't.

Any ideas?

basic carb settings are both screws turned right in then out 1 turn
that should get you running in some fashion then they need tweeking

try yours counting how much you turn them and see

Thanks will have a look at that. Now I've noticed that it's leaking oil from the chain oiler, any ideas on where to get gaskets bar stihl dealer?

One of the things that can cause this is leaky crankshaft seals - cheap enough but quite a lot of work to replace.

Thanks for that, will look into it when I get a chance.

I also have a jonsered 630 saw, only the other day started to run a bit queer. It happened when I refilled with petrol/oil mix, was using the same mix before and no problems.

It doesn't seem to be idling smoothly and tends to want to rev more.

Any ideas?

Quite likely a partial fuel blockage I'm afraid, as a result of some gunky or jelly-like bits in the fuel. In theory the answer is to take the carburettor apart and clean it, but they are such fiddling little things on a chainsaw that it's all too easy to create more problems than you solve. Having said that:
a) empty the current tank of fuel.
b) screw the slow running jet fully in and count the exact turns and fractional turns, then unscrew it fully, and finally re-set it to where it was originally.
c) repeat b) with the main jet.
d)re-fill with known new petrol and good new 2-stroke oil.
Try again.

It may not work, but there's a fair chance it will.

Thanks, will do, you seem to know a fair bit about these :thumbup1:

I will let you know how I get on.

Would it not run right if the exhaust muffler was loose?
