I worked on the accelerator adjustment. I changed the holley CAM from 2 to 1. I tightened up the CAM adjustment (hopefully I didn't stretch the diaphram). But still it hesitates and occasional backfire.

The accelerator jet is only 25. I'll increase it. They recommend by three, so .028. What is yours set at?

Thanks!
