Are you running the stock Carter Carb? Are you buying a replacement mechanical? I think my factory replacement mechanical put out like 11-13, cause when I went to a Weber I was told I had to have a regulator on it down to 4 or something like that.

I got it, and have to return it now, battery just wasn't turning the motor fast enough. Guess i just needed a new battery, happy i didn't install the electric pump.
