Title: carb percolating on '53
Post by: rex on May 15, 2015, 12:20:38 PM

Dear Group,

After a long hiatus I recently purchased another Kaiser and am happy to be involved in the group again.  I am having great difficulty starting the '53 after it is hot, and I can see and smell gas percolating into the intake when I turn the engine off.  My mechanic and I installed a new kit from Daytona Parts, but there was no improvement in this condition.  The carb itself was about like new when we put the kit in.  Can anyone give me any pointers on solving this problem?  This car has the Carter 2052 SA carb on it.

Thanks!

Rex

Float set too high? I have started setting my floats slightly lower due to the gasoline changes.

Hi, Paul,

I have tried lowering them one time, but I am going to try again.  I was wondering if the intake needed a really thick gasket or heat shield?  Thank you for the advice.

Rex, I had that in my ol' 51 Studebaker six and found a heat shield they used.  It did solve my problem.  I also had trouble with vapor lock on hot days and put an electric fuel pump in the line and flipped a switch under the dash when it would begin to chug.

Thanks, Tom!  We just discovered that the rebuilt fuel pump we installed is delivering 10# of pressure, so that is probably contributing to the problem, too.

On some of the Kaisers you could cut down the fuel pump pressure by stacking extra gaskets between the pump and the block. The service manual tells how to do it. The extra gaskets move the pump out away from the block and shorten the length of the pump's stroke for less pressure.

I can tell you from experience if you omit the steel fuel pump spacer on the Henry J pumps, the carb will not handle the pressure.

Thank you all for your help.  I installed two carburetor base gaskets with a steel plate between them, and this helped the problem quite a bit.  I am not going to try your suggestion about the fuel pump spacer.

Thanks,

Rex

Oops, I meant to say that I was going to try that suggestion about the fuel spacer!
