I never rebuilt the acc pump wen i did the carbsI can tell you if you keep doing that you will probably damage the engine.
I agree with Bow hunter in that it is probably a leaking needle and seat. I would also make sure your accelerator pump works and your gas tank holds pressure.
How do i check ?You need to make sure the accelerator pump is squirting into the top of bot carbs.
After you put the carbs back together you make sure they can hold 10 psi without leaking.
Im good once it punches after few minutes of playin with the throttleMine was caused by failing fuel lines with cracks. Air was causing the bogging and I could feather it on the top end to get up to speed, but no responsiveness. Make sure you hoses are not cracking around the hose nipples.
How do i perform the pressure test ? Is it the same as pop off test ?You need to make sure the accelerator pump is squirting into the top of bot carbs.
After you put the carbs back together you make sure they can hold 10 psi without leaking.
Can i do it while its still on the motor ?No, with the carb back together you plug the return fitting and pump 10 psi into the inlet. It should hold 10 psi forever, this is to make sure your needle and seat isn't leaking and flooding the engine.
The acc pump is holding 4psi tooView attachment 35626View attachment 35627No, with the carb back together you plug the return fitting and pump 10 psi into the inlet. It should hold 10 psi forever, this is to make sure your needle and seat isn't leaking and flooding the engine.
Didnt get a chance to check yetAny updates? I'm having a similar problem. Should the carb hold pressure when pumping into the return fitting or just the inlet?
