Just got off the phone with Barry Grant. I was told to try lowering the fuel in the site-glass (Float adjustment) and maybe raising the Idle RPM. Also They want me to double check my timing. I have a feeling the floats may be the culprits. I'll let you guys know. If anyone else has some input, please let me know. The vacuum is the biggest problem with the cam, but MAN WHEN YOU STEP ON IT, IT's WORTH IT!!!!!!
