46mm Weber jetting for a 3.2
I'm converting my 3.2 to 46mm Webers & crank fire ignition. Anyone with a similar set can tell me their carb set up?
venturies: main: air correctors: Also total advance on the ignition. It's a Electromotive HPV-1. I'm using SSI's and sport muffler for the exhaust. I'll fine tune it with an LM-1, I'm looking for a basic set up to get going. thanks. |

I'd start with:
38mm venturies 160 main jets 180 correctors 60 idles Make sure the fuel pressure is at 3.5 psi and the float levels are PERFECT. For the HPV-1: You need to be conservative since that 91 octane gas is marginal in hot weather. Use no more than 30 degrees total and around 18-20 degrees at 3K. Less is More when using CA pump gas,.....
