I posted earlier about a Tecumseh 4 hp vertical shaft engine with an auxiliary horizontal shaft. The engine code is TVS115 56022B. This was a tech. shop engine, meaning students took it apart and put it back together but it had never been run. I have picked up a few of these engines, both the horizontal shaft and the vertical shaft, mostly B&S but this is the fist Tecumseh dual shaft like this one I have gotten. It was in parts when I got it.
It went through it and got everything together on it and it was hard to start but I did eventually get it started. It ran for a couple of minutes and then I shut it off. I tried to restart it but it would not start and it was kicking back on the compression stroke, jerking the cord clean out of my hand. I checked and sure enough, the flywheel key was sheared. I replaced that, it was the "L" shaped key. It was still kicking back and would not start. I have checked the valve clearance, both set right around .006. I have checked the linkages on the carb, it all appears to be set right and working properly. I checked the ignition gap and it was correct. I took the plug (J19LM) out to make sure no oil was causing it to lock up. I had already removed the valve cover, checked the piston and valves and put in a new gasket. As a last resort I split the case and checked to ensure the timing was set correctly on the camshaft, and it was. I went ahead and put in a second new flywheel key, just in case.
In spite of all of this the problem remains, still kicking back and will not start. It is getting spark, it is getting fuel. The muffler is new, OEM for that engine.
Any thoughts or suggestions?
