Al that's a Pro Systems carb? WTF Patrick? He should know better.
I'll tell you...I've had him on the phone more than once and I was never really comfortable with him. Just can't put my finger on it. But I am quite the prick so it may just be me.
FWIW, for what you paid for that turd, you could call Thumprdart (Dominic) and he can do you a custom, one off, fully tested carb that will work.
If you want Dom's number you can PM me for it.
