As a long time friend told me, Aj Watson, don't let fuel injection intimidate you, it is simply a series of leaks and bypasses, fuel supplied by an engine driven fuel pump, which means that you have a speed regulated pump. There are many adjustments that can be made without taking it apart, and also quickly. It takes some thought to figure out how it works, but not impossible, I chose Hilborn because it was a long time ago, and they have some really helpful techs, who are interested in your problem. There are several that are really good also and willing to help, I used to work with Tim Engler on several occasions also, he is super also. I wasn't having any carb issues, but the mechanical injection really improved performance as well as fuel consumption, I'd never look back. Bob
