my engine seems to be dead off the corner... once it gets over 4,500 down the straights it comes alive and runs great,
I borrowed a friend carb last weekend and the engine ran much better.
What could be wrong with this carb? I rebuilt it a couple of races ago trying to cure the problem.

did you set it up with a vaccum gauge? What does your plugs look like with your carb. Too high float or too rich maybe?

quiet a few thing to cause this.
not enough gear
timming
uneven cylinder pressure
flooding out

run a comp check,read plugs, and set timming.

thanks for the replys guys,
B4: The plugs look good, they really look a little leaner then I normally run
I set the floats so the fuel will come out with a gentel rock of the car
SC1: I put more gear in the car, and it didn't help , I am about to run past my upper RPM limit.
And I have moved my timing up and down a few degrees also tried a different timing light and it didn't help

The guy I borrowed the carb from ran mine in the heat saturday night and it did the same thing to him,He thought his car seemed to be starving for fuel,
could the power valves be a problem?

Are you sure it's not the wrong cam? I bought one years ago that a guy said was "the one I needed". My car was a total turd off the corners. Found out the cam had way too much duration. Bought a diff. cam, & the motor really came alive. Just a thought

Scanner,
At first I was thinking that too, I messed around with cam timing and such, but
when I switched carbs , the engine ran great.

You said "I set the floats so the fuel will come out with a gentel rock of the car".

Is this a holley? what you need to do is
open the site plug and rev slowly the motor
up in rpm. see if any fuel comes out the site plug hole. if it does, your float level is too high.
