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

What you need is the Cool Carb heat shield. Google it and you’ll find it.

There are two parts to it, but you can just use one. I always use both of them, because it’s relatively cheap.

That carb has issues with heat. I always block the heat crossover in the intake manifold because you don’t need the heat in the first place, and it pisses the carb off in the second place.

That and the Cool Carb heat shield is the best bang for your buck.

You think I need a heat shield for the carb, when the carb isnt getting hot? Before I added the spacer it was hot to the touch, now when it dies its cool as can be.

My heat cross over is blocked off as well.

I had this carb on the past year, and never had a problem until I redid the engine and engine bay.
