Re: New carb for 220 gpu

I have just done the same thing. I have the Holley 500 2 barrel on top. I have found that the #73 main jets that came in it were way to lean. I have just put some # 78 in, now I need to run it to see if this is any better. Anyone else been able to dial one in yet to help us get closer?

Re: jetting 0470 gpu

Bob, a lot of folks suggest the 77 jets. I have 76 jets for my Holley 500 on the single mag 220 GPU. The previous owner told me his work around fuel problems, like not starting when hot. I had the magneto rebuilt and all those so called fuel problems went away.
