Fixed one problem now I have another.
Ok I found my air leak which I did not know I had other than the engine leaning out when it warmed up. So I fixed it and now I have a whole new problem.

The engine will not start and anything but 3/4 throttle and gas spews out the intake like you would not believe.

I have closed off the low needle and expected a run away but it didn't make any difference it still was spitting fuel out of the butter fly and wouldn't run under 1/2 throttle.

The bad thing is it started perfectly when it had the air leak!!!!!!!

Any ideas why the carb would be spitting fuel while it is running?

Never mind I found my problem. Somewhere along the line of tinkering with the carb I damage the Low needle screw threads. I reworked them with a dremel wire brush and the looked ok. Long story short the needle was not going all the way to the bottom when I tried to set it. My 1 1/4 setting was really about 3 turns off bottom. I kept measuring the distance and it wasn't adding up. I finally ran it in with a bigger screw driver and it finally hit bottom. Set the needles back to factory and pulled it twice and it was running.
