Rototiller Rev Surges
The Briggs and Stratton engine on my front end rototiller is surging. The revs surge at all throttle positions and while both idling and under load. It is only 2 years old and I perform standard maintenance before and after each season. The air filter and pre-filter are clean and it has fresh gas. The power output is good, but it is always revving like it is running out of gas. Does anyone have any ideas?
