I recently bought a home-built splitter and need some trouble shooting help. It has an older 5hp B&S;, a ram that is waaaay tooo long, and regular car/truck tires. I pulled it home at 60 - 65 mph and it pulled fine. The problem is that the load on the ram kills the engine. Do I need more engine, a tune-up, or is it the single stage (I think) pump. I can split with it. I tried it out on some big gnarly elm I cut this winter and it will split it,,,, I just need to "goose" the valve in-out-in-out until it starts to split. What would be the cheapest route to make this a more usable splitter?
