Thanks everyone.
I had planned to install a 4 bbl on a F4B manifold this winter but since the
Holly 2 bbl
became a problem, I moved up the 4 bbl installation to...next week.
I went by Summit Racing and picked up an Eldebrock Performance Carb, model
1404 with manual choke
and delivers 500 cfm.
The carb is new not remanufactured so it ought to work, right?
I am also moving the coil from the factory location on top of the intake
manifold near the gas line, to
a cooler and safer location near the generator.
Thanks again for your help,
Allan

about 12 bucks for a new float its not worth guessing.

regulator anyhow. i keep a mechanical gauge on a long line that can come into
the interior in my tool chest for testing/diagnosis. actually two - one for
carbs and one higher range one for injection.
