I have a 99 EZGO TXT that came with a camp site that I purchased. It has a 6inch lift and 12in tires. This buggie has like zero power on hills. It does pretty well on the flats, but as soon as it starts up a hill, it just completely dies down. So far we have, changed the air filter, spark plugs, fuel filter, fuel pump, replaced the fuel lines and clamps, changed the oil and filter, installed a new carb, replaced the clutch with a high torque clutch, adjusted the governor, checked the compression (reads 150 for both cylinders). Nothing has really made a difference. It does have a slight pop when you let up off the gas. What am I missing or am I expecting something out of this buggie that it isn’t capable of doing?
