Okay so we got the splitter from my father last fall. It worked fine. Split almost a cord of wood. And then put a tarp over it for the winter. Went to use it a few weeks ago, put new gas in, and cleaned the carb and it stalled on startup. Checked the gas tank, had fuel and oil in it. I think. So I drained the oil, and tank and put new in. Bought a new carb and newspark plug. Now it sometimes runs on low RPM, but when moved to high it surges and stalls. It has a new fuel line as well so no blockage there. Ariens 27 ton paperweight, with the Subaru Sp170 6.0 motor. This is really slowing down my projects for the summer. Any advice would be greatly appreciated.
