Rebuilding a golf cart is a complicated matter. There is quite a lot that goes into getting your engine ready to run. This becomes more true if this process started because of a failure that took down the operation of the caddie. Now, not only are you in for a teardown and repair, you have got to figure out what caused the problem in the first place. We get many calls stating that their cart runs fine when it gets gas, but it has to be gravity fed to the carb to get it there. Your knee jerk might be the fuel pump, but don't count out parts like the Yamaha Flywheel Crankshaft Seal for G1 models. If the pressure in the case drops, the pump cannot do its job.This golf cart seal is part of a significant rebuild; if this is not a process that you are familiar with, consider getting a Yamaha OEM manual to help with the process.
