Thank You. That is the information I was looking for. I assisted with doing a valve job on this car with my Dad about 40 years ago. I am going to have to do a little research to remember the process, if the gap was set wrong back then, it was probably my fault.

I just finished a compression test on my 1946 Clipper.

The compression range was 70-85 PSI across all the cylinders except cylinder 4 was 45. When I put oil in the cylinders, compression went up to 85-90 across the cylinders but Cylinder 4 stayed at 45. My understanding is this points to a valve issue or head gasket.

Is there anything I can try with the valves specific to this cylinder before ripping everything apart for a rebuild?

Thanks for the clues. It appears what I have on my 46 Packard is something called an ACON-O-MISER which appears to be a combination fuel filter and fuel economy device of some sort that was used on 1958 Cadillac. The input is a vacuum line that goes to the exhaust manifold which is how it was hooked up in my car. But I'm suspicious that it is not working correctly and causing my carburetor to flood when the engine becomes hot. I see you have a heat shield over your manifold, probably to solve the same problem I am having.

I have a fuel filter for my WDO carb and it has a outlet on it that I am not sure what it's for. I believe there was rubber tubing on it and maybe it's an overflow or return line of some sort. Does anybody have any ideas. Picture attached.

I am interested. I have a barn near Wentworth.

I drove my 46 clipper yesterday about 50 miles and when I stopped my battery did not have enough charge to turn the starter. I suspect that there is an issue with the charging system. When I jumped the car it started right up. I am looking for advice on how to troubleshoot this problem to determine if its the generator, wiring, or regulator. Thanks in advance.

I am only using the electric fuel pump to prime the engine. I recently replaced the mechanical fuel pump with a rebuilt one and I actually rarely need to use the electric fuel pump at this point.

Forum ambassador, I think you are setting me on the right track. I don't have 100% confidence in the guy that last rebuilt my carburetor and I have been so focused on all the discussion around the issues with new gas that I wasn't seeing the forest through the trees. I expect there are plenty of these Carter 2BBL carburetors out there dealing with new fuel if they are tuned and rebuilt correctly. I am going to do some visual inspection and maybe get some professional help as my next step.

I know this is a common topic but one that continues to frustrate me. I continue to have problems starting my 46 deluxe clipper after it is hot due to what I believe is fuel percolation due to the new gasoline. I already have a rear mounted electric fuel pump, I have read all the forums on how to start a warm car by not pressing down the gas pedal for 3 or 4 seconds and then slowly depressing a third of the way. I have tried adding lead additive to my tank and a cup of diesel to lower the boiling point, but the problem still persists and I frequently still need to let the car sit for 15-30 minutes before she will start. Although I understand these idiosyncrasies in my classic Packard, my wife and other passengers don't seem to appreciate it as much. Is there any permanent fix to this problem, new carburetor rebuild kit that works with the new gasoline, etc. that anyone has seen.

My 46 Packard has a bypass oil filter system with the canister type filter. Do you replace this at every oil change like new cars are they good for a longer duration?
