The head i replaced with right now was used for about 10k miles, SS valves, but theres is a significant amount of valve tapping. Will a valve adjustment help my flooding issue?
a valve adjustment is vital to a good long engine life anyways...as far as it adding to much gas, well it might be allowing too much air in, and then the ecu would reply with more gas, which could be flooding it out....since the head was swapped, make sure all the vacuum lines are free of pinholes, especially the ones to the fpr....i am running a walbro 255 on mine, with 345cc injectors and an aem fuel filter....way too much gfas for an NA car, but my vafc will take care of it....list the full setup of your car, and i will pass it along to a few to see about getting it fized...peace
