I just purchased a 2003 Max Buffalo. I am new to aatv ownership and know little about the t-20. It has 50 hours on it and has sat for a few years. It seems to drive fine on flat ground however I could not get it to drive up the ramp to the trailer I used to get it home. A friend pushed while I was driving it up the ramp to get it on. I have yet to really look into potential issues with the Buffalo and was wondering if anyone has any suggestions on where to start looking into the low power problem.

I have not done much to it yet. Before starting it I put fresh gas in it. The tank stank like very stale gas and there was only a few oz of old gas I could not drain out. I pulled the plugs and they appear somewhat fouled. So I will be getting new plugs. I will be changing the fluids also. Any other maintance situations would be welcome.

Thanks.
