I have a 60 in my shop from a neighbor that I can not get to run.The tractor set for about three years and was not running good then.We put it in the shop and cleaned the gas tank and had the carb rebuilt by a professional. New points,plugs and condenser were installed.I have good spark at the plugs.No go, so we removed the valve cover to find a stuck valve, freed that up and still no go.Plenty of gas to the carb(we rebuilt the sediment bowl assembly as well).I can not even get any smoke.The bypass starting has been removed so it is 12 volt. Tonight I took the carb of my 630(it runs fine) and put it on the 60 and still nothing.I even sprayed either in the air cleaner and no go.The intake and exhaust manifolds were both replaced several years ago and appear good.I rechecked the plugs and put a tester on the wires while turning it over and it has spark.What should I do next? Is it possible that compression is to poor to start? I do not have a compression tester but can get one Friday if someone recommends it. What compression should it have? It seems to have plenty of air coming out of the spark plug holes without plugs,but that would only be a guess and a poor one at that.I am using Autolite plugs, I think a 386.If I can supply any more info just ask as I will check mu computer several times this evening.
