Re: Engine dies under acceleration

Bob - couple of suggestions.
1. Remove the fuel line to the carb and check the brass screen in the carb. I have seen cars that have sat for a long time develop crud in the tank, and upon heavy acceleration, suck the rust particles up to the screen and clog it. Mild acceleration wouldn't cause that, but full throttle will.
2. Check the fuel filter and/or replace it.
3. Drain some of the gas out into a glass dish - your wife's best Pyrex pan will work well. Let it set a few minutes and see if you get water or rust chunks in the pan. If so, drain out about a gallon or so. Filter that and run it in the lawnmower. If you continue to get rust, you may want to consider removing the tank and taking it to a radiator shop to have it boiled out and coated. I did this on my 39 and it cured the crud problem.
4. If you haven't already done so, swap the coil for the one in the trunk. I did this just recently on the 51, as it was missing during high speed runs and it cured it.

Good luck - hope you had the car inside during the last hail storms in Colorado!
