Hi,

sorry your having problems. Did you change the fuel lines from and in the fuel tank? If you did not the bubbles from the needle to carb. could have been coming from the tank in the first place.

I generaly check out a tank under water, put it under water and blow air into one of the lines and look for air bubbles. I put a new piece of line on to blow on.

Oh by the way, go to low caps for the posts , its easyer to read.
