Have I reversed the fuel lines on my purge bulb?

You answered my next question-where to find another diaphragm. Thank you.

carb diaphragm replacements aren’t expensive. Good thought for shtf teotwawki where we somehow still have plentiful fresh fuel for saws though.

Looks like it’s a Zama C1M-W47 carb. Double check that, but once tou know the carb model it’s easy to get the rebuild kit.

I replaced the purge bulb on a poulan pro pr5020. The saw sat unused for a while and the bulb cracked. Prior to that, the saw ran great. After I replaced the bulb, I can start the saw easily but it stalls almost immediately as the gas I choked into the carb burns. choking the saw to start is like giving the engine a shot of gasoline. After it starts, the saw quits. Could this be because I reversed the fuel lines? I can draw gas into the carb to start but I can’t get any fuel from the tank to the cylinder after that. Is this a bulb /fuel line issue or something else?

Check your impulse line before going to far. It could act like that if it was broke or disconnected.

Any progress?

I finally CURED similar issue on Poulan after many tried, I trimmed 1/8" off the 1"+/-long fuel line between primer/ carb; it straightened fuel LINE, and took out slight bend/ crimp, and ALLOWED FREE FLOW OF FUEL (and this the SHORT version of story). GOOD LUCK
