B20B Webber carb help
I am running a 1969 B20B in a 544. It has the Webber conversion.
The engine is really running rough at start up. Choke is killing the engine instead on making idle faster. Dwell is at 62. Timing has been tried from 10 to 16 with little difference in performance. Lash is adjusted correctly. Even when it warms up it shakes a bit. I am left with carb issues. It also is bogging down under acceleration. I think it may be a jetting problem. Carb has been rebuilt. It is a 32/36 manual choke. Right now idle it is jetted, 60 primary, 50 secondary Air jets are 150/150 Mains are 175/170 I have used idle jets in this combination 55/55, 50/60, 60/55, 55/60 I have used 145/140 on main jets. Does anyone use this carb and what jets do you use to make it work well?
