This year my nearly stock '54 Customline Tudor has decided that it doesn't want to start more than once every 3+ hours!

In short; I start her up, go for a ride (any time duration or number of miles) and shut her down, when I decide it's time to get going the old '54 thinks otherwise. It could be a 3 to 12 hour wait and I frequently drain the 6 volt battery while trying to get her started. Funny thing, the battery will be ready hours later when it does decide to turn over.

I've been told it could be vapor lock, but I'm not having much luck finding a fix specific to the '54 239 Y-Block. I'd have to believe that many club members and '54 owners have experienced and found a fix. Please fill me in . . . I really would like to cruise when it's my choice, rather than my cars.

Thank you!
Michael

If it happens again, take the air filter off look down the carb and work the linkage. if you see gas or hear gas squirting down the carb, then it's not a fuel issue.

Then start checking spark - specifically the coil. Another cause could be a bad condenser in the distributor - if you replaced it recently, it could be bad. Lots a chinese condensers on the market and they are crap. If you have a condenser that you took out but was working ok, put it back in.

Does it crank good when this happens? if not, then there are items that need to be looked at.

Thanks for the feedback. It does crank over just fine until The battery begins to wear out.
I had forgotten about the HAMB forum. I'll pull out the service manual and check each suggestion from simple to complex.
Hopefully I'll be back with an update next week.
Thanks!
Michael

I had the same problem and it is now occurring to me that my cause was the float being out of adjustment on my carburetor. I had a situation where it actually overflowed the gas onto the intake a couple of times and to this day I still don't understand how the car didn't catch on fire.
Anyway, I believe it would shut off the gas going to the engine when it acted up. It's just a thought, but you might want to check it out. I'm sure someone on here would tell you the best way to do it. I can't remember without looking at mine, which is completely covered up right now.
