Air in fuel line
Ok, I have searched and it seems as thought bubbles in the fuel line from the regulator to the carb is a normal occurance. My YS 110 has bubbles at full throttle and as I approach idle, by the way anything below about 2700 it just surges and dies, the bubbles just take over the entire lenth of fuel tubing leaving no fuel in the line that i can see. I have richened the low end all of the way with no luck. The motor leans out and dies. I have flown the motor with the needle (high) rich and it still leans out while flying until it gets hot and quits. I am tired of dead stick landings, please heeellllllllpp!!! By the way, I have tried Byron, Coolpower, and Powermaster 20-20 fuel with the same result everytime. The plug is a OS F.
Should I inspect the diaphram? Or send it to you? I am open to all suggestions. Thanks.[&o][&o]
