... It was a Q950 Stock jetting was way to rich...
How much did you have to lean it out from the standard tune? I'm a little surprised you said it was too rich from what I recall the out-of-the-box settings are.
I believe it was 4 front and rear
I am not surprised now by this . I had to pull 4 or 5 jets out of the front and maybe 2 rear when I went from 440ci to 505ci. Motor just works the carb harder especially if carburation is a little undersized .

PS : my 505 with a hair more comp and bit more cam makes 600-620 FWHP . With a 4150 carb , mufflers and exhaust to diff . I am not sure this one will go too much more .
