I was wondering, if the umbrella check valve that is installed with the accelerator pump and diaphragm was broken could this cause a lean condition at high rpms or anytime the secondaries were open?
I've been trouble shooting my tuning problem and think I found it.
I was going to swap jets on my secondaries and when cleaning the bowl out I noticed I couldn't see the nipple on the check valve sticking through the hole. With the bowl in my hands I pressed the accelerator pump lever and fuel shot back into the inside of the bowl through the spot where the check valve nipple would be. I just want to know if 'm correct in thinking this. Thank you for any input.
