Thread: I am so STUMPED!

soooo... Dropped the gas tank replaced mesh strainer, blew out gas line, replaced all rubber gas lines, inline fuel filters.. Check timing with timing light...mark seemed to be slightly bouncy... Still running poorly I'm broke, I'm tired and going to Bed now!

On mine, the sock had collapsed and it looked like it was bending to the side and covering the pickup tube. My fuel pressure was very erratic, sometimes it would be right and sometimes it would be low. I couldn't find a replacement sock, so I cut the sock off and stuck an inline filter before the fuel pump. I used a coarse stainless mesh filter so there wouldn't be any restriction. I think this is better than stock because you can...

rebuild the carb, sounds like the jet could be plugged. Will run on the idle circut and as soon as you try to open the throttle it goes way lean and dies. You are getting fuel into the carb right? sorry just went back and noticed that you did rebuild the carb. Now I am thinking maybe water in the fuel.
