BBK100 installed. It runs but not quiet smooth...PLEASE HELP  By  ice77 (Read 1,140 times)

I have installed 2 of that same kit and each time I have opened up the A/F screw until it falls out...I have observed fuel being "spit" out with every pop through the venturi and have been told that it is too rich hence the need for more air.  The first engines popping was solved by installing a carb off a 150...and it runs nice...problem is I don't know what size this carb is which brought me here looking to see if anyone knows what is the largest venturi size a 50mm bbk can handle?
