My fuel injectors on my holley TBI system,(1990 burb with 6 inch lift, 37's, crazy trans, etc) is adding too much fuel into the mixture. So much that it floods the intake and now it will not start. I was wondering what could be the problem, fuel injectors, fuel regulator (someone at work said that will be the problem) or something else. I have taken it apart and cleaned, the injectors looked good as well as everything else. Any help will be great. I have also been thinking about switching it to carb. Has anyone done this swap, what suggestions would they have.
