My set up is very similar to Stefan's. With the exception of the idle holder which is a 120 and the main jet which is a 155 (couldn't find the 150).

Choke 40
Main jet 155
Emultube F15
air jet 120
idle jet 65
holder 120
pump bypass .00
screw 1 - 1 1/4 out

Virtually no popping or backfiring, but still have a very slight low speed gurgle or stumble at around 2000 rpm which passes very quickly. But my car lives between 3000 and 4000 anyway so no big deal. I'll still keep sorting.
