I also have a SpeeCo splitter. Mine is a 25 ton. About 20 years ago I did some appraisal work for a guy getting a divorce and he traded me the splitter for my bill. I thought he had bought it new, but found out later he got it used, so I have no idea how old it is.
He told me to check it out prior to using it as his kids were mad about the divorce. Good thing, as his son had poked saw dust into the crankcase.
This one has some design failures, as in the fact that if a piece of wood gets away from you on the engine side, it will hit the spark plug. Your done until you replace that little item. If you let a piece of wood get away from you on the other side, it can hit the return line and split it where it enters the tank.
I keep it inside when bad cold, as it is direct drive and hard to start when oil is cold.
Aside from items mentioned above, it has been a good unit and has served me well. That said, it might not start again, but it owes me nothing. It has started to burn some oil, so that day might be closer than I realize.
