Need Suggestions for Club Car Power Increase

If anyone can give suggestions for power increase on standard club car engine it would be greatly appreciated. I have a 80's model and need more speed. Free mechanical assistance, motor is weak, most probably compresion, where is the most reasonable place to get piston and rings and gasket set, and what is most reasonable way to beef up the carb? I am not an expert, just a poor redneck trying to make a hunting buggy, do not have 10-15 k for polaris. Thanks
