Glad it is fixed. Now you know the symptoms.

Unfortunately these crap power valves can strike at anytime? There is something wrong with the "rubber" material they are using.

Maybe it is the ethanol effect?

I'm not exaggerating. I replaced about 10 (I think) in my cars in the last 4 or 5 years.

Webers don't have that issue fortunately.

The "type 2" is a sneaky one and can be difficult to diagnose without taking it out and putting it in a tester.

I have the little Moroso test kit. It has been worth it's weight in gold so far.

Yup. Those "Dominators" are monsters. Two of them sideways on top of the engine are amazing. I could go for that.

Happy trails.
