Ok the motor is broken in and runs well enough.
One problem when the motor is WOT is that I have large bubbles in the fuel line. Actually I would say that there is a break in the delivery of fuel to the carb. Not foam or bubble but large gaps. When I reduce the throttle to about half the fuel delivery returns to normal. Checked all the lines and tank and I have no holes. Maybe it’s vibration but I thought this would be characterized by a lot of small bubbles(foaming). Of course many small bubbles that combine make a large bubble. But I don’t think this is the case. Could this be a pressure problem at WOT?
