Dad's 032AV has a fuel problem. I can start it on choke and can open the choke part way while hold it at full throttle but it eventually acts like it runs out of fuel if I have the choke half, or more, open. It starts right back up though, with the choke half on, and proceeds to "run out of fuel" again. If I open the choke all the way and let it idle it "runs out of fuel" and will not restart without choking.
Here's what I have done, as the saw was in bad shape when I got hold of it.
New fuel filter.
New in-tank fuel hose.
New/used air screen.
Several other parts unrelated this the problem (bar, chain, muffler parts).
Took carb apart and blew out all passages with carb cleaner.
I essentially refurbished the saw. When I gave it back to him it ran beautifully. He sent it back saying he couldn't get it to run. When it came back, neither could I.
Today I pulled the carb off and pulled the fuel pump and impulse covers. I saw that the impulse diaphragm was coming apart around the edges a little, but still looked like there was enough meat to seal. Carb is all clean inside. The needle valve seemed to be stuck closed when I pulled it apart again, 30 minutes ago, and I freed it up. Fuel pump diaphragm seems just fine. The reed valve diaphragm seems OK. I fired it and it behaves as described at the beginning of this post.
The impulse hose looks like it's sealing, but I have not checked it in depth because I'm not sure the best way to check it.
I'm starting to think I should just put a new carb on it.
Is there something I'm missing or need to check before putting a carb on it?
Thanks,
Chris
