I have a 1963 460 L P gas tractor and it was running fine but it has started running very sluggish at high speed. It will run for about 15 minutes at high rpm and then acts like it is starving for fuel. I cleaned carburetor (wasn't dirty or no damage to the inside), did not fix problem so cleaned the regulator (wasn't dirty and no damage to inside), still did not fix problem. If you hook any thing to it , it really becomes with very little power. I am at a loss. Anyone got any suggestions?
