I have been helping a friend with his new G62, and he is having a problem priming it after filling the tank. You really have to flip the prop a lot in order to get the air out of the feed line. The engine runs great once it is started, but it is difficult to start. My G62 primes significantly easier and starts in 2-3 flips. There seems to be only two differences between our setups. He has a loop in his gas tank vent line, I don't. He removed his choke and put silicone in the two holes that the choke shaft went through. Also, my G62 will actually drip gas when priming, his won't. His just doesn't seem to get as wet.

Any suggestions would be appreciated.
