VAPOR LOCK?

[Joel A Campos]

Hi All,

    I finished my 429 transplant (Still a 429) last fall and cannot get the car to run correctly.  The carburetor, a stock Rochester 4gc was fully dismantled and cleaned and put back together.  car starts and roughly idles but when you put in drive it runs all over itself and will sometimes dies.  Then we get to when it get to operating temp and stalls and will not restart until it cools down.  It will crank over and start on fuel directly in throat of carb, but seems to be starved for fuel otherwise.  

This is an AC car and the Motor swap was from a 64 with AC.

The Fuel filter housing has the vent back to the tank and the tank was replaced with the proper vent return accommodations. I guess I will check that the filter housing is not plugged but not a 100% if its actually Vapor Locking or not? 

I'll be the first to tell you that I am not the greatest at tuning up a vehicle, but any help or direction setting up the carb and other adjustments to fix this condition would be greatly appreciated.

Thanks, 

Joel

Hi Joel,

     Do you know how your gasoline is - condition wise?  Do you have water in the gas?  When it runs all over itself, it could be bad gas or dirt in the line.  A clogged needle and seat might also cause some of the conditions you described.

Hi Joel, how sure are you of the condition of the fuel pump?

I had a pump go out on me and I thought I was fighting vapor lock.
