1953 Flathead acceleration issue again
Last week I posted I had acceleration issues on my 1901 yeapot carb. I moved the accelerator pump adjustment to the right from the middle hole and also found the diaphragm for the power vavle was shorter so I changed it out. Took it for a drive and ran awesome for the most part but my volt meter was pegged and it would spit and sputter when it was so I found the alternator was bad, had it rebuild and put on. Now its charging fine but the acceleration issue is back now. I didn't do anything to the carburetor from last week so I don't know what happened. Any ideas? I'm just getting frustrated and confused. Thanks

Multiple issues can be like that. Any electrical parts damaged by the alternator problem? The old standby is start with the condenser.

Re: 1953 Flathead acceleration issue again
Although you are getting fuel to the bowl, check the tightness of the glass bowl and the condition of the cork gasket.
Looseness or a cracked gasket can cause air to be sucked in and can cause stumbling etc.

Re: 1953 Flathead acceleration issue again
The other weekend when I thought I fixed the issue but found my alternator bad the volt meter on the car read high but at idle it when back to 12 but then when I did a check on the system it wasn't charging at all. I thought about the points and everything but if it wasn't charging on my multimeter I don't think it was charging for awhile. My meter on the car is still the original with the wire running through it

Last I knew, Mercury did not use a volt meter but an ammeter. Just what do you have?
