Guys, I just bought this 49 Plymouth. he has a in line six engine. t seems to flood when you shut it down. Im thinking maybe either the needle and seat leaking or a miss adjusted float. What do you all think.
Sorry about the spelling, Some the keys are not working as they should
Will,Check your fuel pump pressure. Newer pumps put out 6 to 7 PSI. Carter B&B carbs like 3 PSI you might need a regulator. when you shut the extra pressure has to go somewhere and that can cause flooding. Norm
Norm has a good point.
IF the car runs ok while driveing that would tell me the float is "ok".If the car throws out black smoke and has no power and fouls plugs,I would say check float level or for being full of old gas.
But if the carb only leaks after shut down,I think needle and seat would be the thing to check first.
Filters on the fuel system,make sure they are good to keep junk out of carb.Have you had the carb open?
IF not,old gas could have gunked up in there and the fresh gas broke that gunk loose and it could be causeing some issues.
I found the problem with the flooding. It had a layer of about 1 or 2 mm of something that looks like very fine sand coating the bottom of the float bowel. It was just enough to hold the float up enough to let the car run but also to hold the needle valve open just enough to allow fuel keep flowing into the system. Guess I will be pulling the gas tank and give it a good cleaning and then adding a filter.
