Need help getting her running again. Sure don't need to, I have many other saws but can't not fix it.
Sitting for over 10 years, Cleaned out all the old fuel and saw starts and runs good until you try to run at full rpm
then it seems just like it running out of gas. If you let the throttle return then it stays running. Will rev until it starts to
die again. Tillotson carb. has been apart 3 times and cleaned and gaskets and diaphragms replaced. Will run with low speed jet out about 3 turns but still will not rev. High speed screw does nothing!! doesn't make a difference if it screwed out 5 turns out screwed all in. Reset the need and seat to run richer and still makes no difference. Have not removed the welch plugs in the carb but carb cleaner seems to squirt through all the orifices? Can't understand why the high speed jet does nothing. What is so funny is that the saw starts good and I can adjust it to have a nice idle. And will rev good and then start to bog if you hold the throttle wide open and will stall unless you let the throttle return.
--Kinda has me stumped. Wish I had another carb to try. Any help would sure be appreciated.
