Percolation? Heat soak? Don't drive during summer??

The only bad behavior it does is it starts to stutter like its losing fuel, but giving it gas doesn't change anything. I swear it sounds as if its running out of gas, but none of the lines are hot and the carb is cool as a whistle when it does it... no misfires, no backfire, no nothing, only stuttering. Ill see if I can't get a video of it today, I'm just finishing up with my patient charts for the day.

It IS running out of fuel. Why it takes 4 hours to restart I can’t say, but when it boils the fuel out the carb is empty. It takes a bit to get the bowls filled up.

Do a google search on those carbs. It’s not a secret. You keep saying it’s cool, but that’s just WRONG. It can’t be. It may not be 400 degrees, but it’s hot enough to boil the fuel off.

I’ve had it happen at stop lights, waiting for damn train and once, the last straw with this one was a long line of traffic last year for road construction and it quit twice on me.

It’s boiling the fuel out of it.
