when I picked it up it had been sitting about 2 years. it has new plugs and plug wires. I dropped the pan and cleaned the inside and inspected pump. installed new pan gaskets, new oil filter new oil. installed new carb kit. cleaned out gas tank and ran new gas line w/ filter. not back firing now, got in time now. its turns over and sound like its just about to start and then the starter kicks out. there is gas getting to the carb. its sounding like its not getting enough gas. this help any?
