Hello Friends,
For the last several months I have been struggling with hard starting issues with my '53 Dragon. The car starts great when cold and runs great; however, after turning off a hot engine, within 10 minutes the car is very, very difficult to restart due to percolating. It always takes about 10 minutes for this to occur, and you can smell the gas. By putting the accelerator to the floor, she will usually start eventually, but sometimes she has to sit for 15 or more minutes. While it's normal for a hot car to spin over some for restarting, I am talking about 15 or more cranks and then a lot of belching and sputtering. Sometimes I can't keep it running during this period, and then I am really stuck until the gas dissipates on its own.
To correct this problem, we have put a new kit in the carburetor, installed a make-shift heat shield at the base of the carburetor, and I even tried adding a pint of diesel fuel to the gas to lower its boiling point (per a Studebaker Club article). Nothing I have tried so far seems to help. I am wondering if any of you can make further suggestions? I love this car and it drives and handles like a dream, but it is nervous driving it anywhere for fear it will not restart in this hot weather. By the way, it did this back in the cool weather here as well. The car runs flawlessly except for this problem.
I am puzzled b/c I have a '54 Pontiac with essentially the same intake set up, and it is never hard to restart when hot and never percolates.
Thanks!
Rex
