Weber 38 jetting
« on: March 17, 2014, 07:47:43 PM »
Has anyone tuned a Weber 38 on a 2.3 Lima? I'm looking for a jetting baseline for a 38 I'm getting from another application. Turbo lower intake and mild Comp cam.

Well, every application is different so I've always been one to start off with stock out of the box and go from there, but maybe someone has a setup similar to yours and can get you closer???..

Make sure the main hi speed AIR jet is right or any GAS jet numbers you get may well be out to lunch. The fuel jetting is based on air jet used.
