Building a log splitter with an Intek 25 horse engine and need to know how to wire it. The original l engine was a a 13 horse but was worn out. I bought the 44t977 but didn’t realize it needed a battery connection for it to run my old set up I just used a jump pack to start it and choked it to shut it off. The new engine requires power to the carb to run . There is a wire harness on the engine with 3 wires to it I know 2 of the wires go to the carb but I can’t find any wiring diagram on line to show me how to wire in a starter switch and battery.I’m assuming I also need a starter solenoid.
