Carburator question

[bly]

Thanks for all the great responses to my post. The carb I have Is a 4150 model I beleive, I purchased it off e-bay, seller said the number was #4779. supposodly rebuilt and dynod. I bought it for 150.00. Installed it, started car and the secondary accel. pump cover started pouring out fuel. removed cover to install new gasket and found diaphram to be old and crusty replaced, (so much for it being rebuilt), then found two screw holes on fuel bowl to be stripped causing leakage, helicoiled, leak stopped. ran engine again, noticed a constant drip coming off of primary boosters. Pulled off again took to performance shop to be rebuilt (90.00) Put back on ran, same accel. pump cover leaking again. took off, heli coils pulled out. Took back to perf. shop and they replaced the bowl for no charge. Put back on, leak gone, tuned carb, shut motor off and noticed fuel leaking out of primary boosters again. Tried to adjust floats to stop leak, no help. I also put some of those clear float bowl sight lenses on, one broke off and now that leaks. Im done with this carb i belieive, I coould've bought a new one almost for what i have spent on this one. I am thinking of a new 4150 650 DP. If I do get new, Is anyone interested in the 750 I have, Will be relatively CHEAP! Thanks again for all your input. Bly.
