The engine will turn about a 1/4 turn then stop. I get a little fuel back thru the carb. The positive from the battery to the solenoid gets a little warm after 3 or 4 tries and I am get a little smoke. Appreciate your help.

From your post, I can't determine if you have fuel leaking in the carb, and possibly hydrolocked the cylinder with gas, or the valves are out of adjustment, and can turn past compression stroke.

Look into the carb, and see if there is a pool of gas. If yes, then you need to remove the spark plug, and either let the gas evaporate, or blow out with compressed air ( do not crank the engine, because fuel will spray out, and can cause static electricity to ignite the fuel), remove and clean the carb, best down with a carb kit, check the oil for gas smell, and change if gas in oil.

If no fuel present, then remove valve cover, remove spark plug, turn flywheel to where piston is just past TDC, and both valves are closed. Adjust valves to .003-.005 intake and .005-.007 exhaust, and see if that fixes the problem.

Thanks for the reply. There is both a pool of gas in the carb and gas in the oil. I have pulled the plug and will change the oil tomorrow. Thanks again for the advise.

I changed the oil blew the gas out of the cylinder and let it sit with the plug out and the air cleaner off plus a quick clean of the carb (spray carb cleaner). It started right up this morning but runs really rough, black smoke coming out of the exhaust and going thru gas like crazy. Can someone help me with the next step?

Thanks
