I recall the old girl would quit for no seemly reason on the road. We waited few min and she would fire up and run fine rest of the day. We figured vapour lock in gas line from hot day, but not the case this year with constant rain and few warm days.
The 32 spluttered doing similar thing but using WD40 which is highly flammable, into the carb mouth, when we first tried to start it, until discovering that two pin hole air holes in the carb neck were blocked. Mine has the orig J4A on it for 32. Once we opened those she roared to life after 40 + years.

So got it to start today! problem was at the fuel pump as suspected. The problem was actually twofold...First there was a small obstruction in the line between the pump and the carb. Gave a bit of a suck and all of a sudden I could hear some air movement but not much. I then realized that the cork gasket to the site bowl had dried out so I could hear air loss from there, Changed that and boom she starts.
NOW FOR THE NEXT ISSUE! running cold all was perfect had it running in the driveway 5-10 mins purring like a kitten. Took it out to put air in the tires and by the time I got there (2 blocks) the carb was leaking alot of gas. My carb is an older Zenith that seems to have only one adjustment screw....
Can I pick your brains again? Carb floats? adjustments?
