"Tiny bubbles in my fuel lines"
I have a ST2300 on a Goldberg Sukhoi. I have put on a Perry carb #5001. I have 5/32 fuel line, large clunk, the whole nine yards. When I point it up I see bubbles in the fuel line to the carb. Do I have a hole? or is there some other problem like not enough tank pressure? I have a Bisson Pitts muffler with one stack blocked off. 15% Byron fuel. MA 16x8 @ 8300 rpm.
