Cliff Ruggles:
The cup is what he's talking about that sits in the aneroid area. It doesn't need to be there, but really hurts nothing that I've seen if you don't use it.
For sure leave the splash guard in place above the N/S assembly.....
Mr.Pontiac:
Ok, Thank you
Mr.Pontiac:
Ok, small update, cleaned my washable fuel filter out, found very little depri if any. Removed top of carb.and took out needle and seat, drilled it out to .140, from my machinist days probably went couple thousand. Bigger. From the .135.I had g hanger with your trick secondary rods and kicked ti up to L, should rich-n up secondary side. Taking car out soon, I’ll post results.
Cliff Ruggles:
Didn't you post above that it was already drilled to .140"?
I'd go to .145 or even .149" for what you are doing.
If that doesn't work you need to address fuel delivery to the carb. Are you running a sumped tank already?
What pump?
Is it behind the tank?
What size fuel lines?......
Mr.Pontiac:
Holley blue pump, yes tank is sumped, running no.10 lines up to pump, then no.8 up to reg.from there short 8 inch long no. 6 to carb.
