I still have the old Tecumseh in my 1816. I really don't want to put another $2000 in this machine, but it is handy. When I was in Harbor Freight last time, I saw a 22 horsepower V twin for about $700. The reviews are pretty good. So here's my concern. My machine doesn't run now, and I forget which way the engine turns. The Harbor Freight says that it turns counter clockwise looking at the PTO. Does anyone know which way the Tecumseh turns? If it's the other way, is there a practical way of dealing with the situation?
