I have been having problems with my Spitfire sputtering like it's running out
of gas above 50 mph on hot days after it runs for a while at that speed
especially going up hill. If you let up and drop down in speed it runs fine.
Also runs fine at lower speeds even when it's hot. Runs alright above 50 mph
when the temperature is cooler.
I have a Weber carb with a mechanical fuel pump with the factory heat shield
under the carb.
Anybody have any ideas? Fuel filter, fuel pump, carb, vapor lock? Can vapor
lock happen at higher speeds?
I'm going to start with new fuel filters.
Thanks for any ideas.
