[Chevelle-list] Hot Restart

[Jim H. Thompson]

Warm day ...Vapor lock

 

What kind of fuel line? Is it run in stock location?

Hi Rick,

 

No and it sounds like there is no spark, no sputter or response of any kind.
Both times it happened in the sun on a warm day with no diagnostic tools at
hand.  I can cure that on the next outing.

 

Thanks,
Dennis

  Have you checked for spark at the times it won't start?

Good thoughts from John.  Maybe the needle is sticking open or float
sticking allowing excess fuel in the carb from pressure in the line when
it's shut off.
