I just joined this group yesterday and it seems to be populated with genuine good guys that want to help each other. Good. The lack of attitude is refreshing to say the least.
I inherited a non-running 028 WB and recently decided to resurrect it. It's an older model with the gas tank as part of the metal handle. As it stands now, I can get it to act as if it wants to start when choking it, and to try to start and make maybe a dozen revolutions before dying when the control is moved to the run position. Compression is good. So far I have:
Installed a rebuild kit in the carb (Tillotson HU40A) including new diaphragm, gasket, fuel pump diaphragm and gasket. Removed both low and high adjustment needles and sprayed carb cleaner through the passages as well as every passage in the carb. Both adjustments are one turn open.
Removed and inspected the rubber intake manifold and the impulse tube. Both look perfect.
Replaced the fuel line and filter.
Removed and inspected the muffler and exhaust port. Both clean. There is no screen in the muffler BTW. No noticable scoring in the piston/cylinder.
Replaced the plug. Gapped to .020.
My questions are these:
How likely is it that the crank seals are leaking badly on this saw? Can crank seals leak badly enough to lead to a no-start situation such as this? How difficult is it to replace them?
Even though there is spark present, could the points/condensor be bad?
I was so frustrated last weekend that the whole shooting match almost ended up in the dumpster. Luckily, I cooled down.
Any help that you all could send my way would be so appreciated.
Thanks All.
