Default For those of you with Webers...interesting jetting finding
I have been doing my final tuning to my Weber IDA setup, and was struggling with the transition and some general balkiness. On whim I changed the pump exhaust jet from 55 to a 50, and wow what a difference. Pulls hard all the way, no sags. This engine spools like a crotch rocket! So if your having some problems consider the exhaust jet. For refererence my current settings are:

Idle: 60/120
Main: 150/F7/195
Choke: 37
Pump ext/shooter: 50/50
Screws: 7/8 turn

351W milder cam, 5degrees overlap
