Quote: the lean condition on top end may be high speed air bleeds. try two sizes smaller. that should richen it up a bit. do this with an air/fuel gauge so you can see whats going on.
how do you change them on a car with pressed in bleeds? Do i have to try and drill the old ones our and screw in the screw in type? I'd hate to do that on my original carbs. Is there a way to change something on the Promax jet plate that would accomplish the same thing?
