i have a 89 johnson 60 horse that leaks gas out of the black housing at the front of the motor when it is tilted all the way up. when it is tilted up it is almost horizontial.the housing i assume is the air intake ? the cork gasket is cracked at the bottom where the gas leaks out. is this going to affect the perfomance of the motor at all? i plan on replacing the gasket sometime. also i assume it is leaking the gas out because of being tilted at to much of an angle? let me know what you think thanks alot
