Chainsaw Repair

Low speed contributes to the gross fuel supply at full throttle as well. Richer low speed will = more on top too

Yes, quite correct. I should have said I didn't think it would contribute as much as it does at higher speeds. But then it doesn't take much gas to run fast under no-load conditions, does it? Especially since the chain is off.

Apologies,

Have you tried opening up the low speed needle to where the saw idled and accelerates well and cut wood with it? 

No, again you make a good point.

I was waiting for my wife to sharpen my chains before I put them back on. I hate to admit it but she has a lot more finesse with a file than I do. An old time wood cutter around here let her place her hand on top of his as he sharpened a chain and she picked right up on it. I can never get a chain as sharp as either of them. Too clumsy and heavy-handed I guess.

Nonetheless I should at least put a dull one on and try it out and will do so when I get home.

Thanks,

Sounds like a leaking impulse line to me.  Runs with rpm but no bottom end tickover or power.
