Engine running away after carb rebuild....

I just gotta ask this, don't take it the wrong way; Have you verified that the throttle blades are closing when you believe that you are manually closing the throttle?

Haha, don't worry man, I got a pretty thick skin. It was @pishta who got me to think clearly. Normally, a carb "rests" in it's closed state. I wasn't thinking about the fact that this thing has no return spring built in and what you are suggesting is EXACTLY what I did. Tt didn't matter that i was running it manually because I was operating it backwards. I A$$umed the carb was closed in it's resting state when it was in fact wide open. Big old face palm moment to be sure!

Once I pulled my head out of my arse and did it the correct way, with a return spring connected I might add, it worked great. +1 for my kid rebujilding the carb right. Didnt' find any vacuum leaks either, unless you count the one in my ear.

Thanks for the tips, suggestions and most of all patience. I learn something every time I ask a question here. A serious group of awesome folks.
