Boss Drives 37 EFI Briggs and Stratton
I got a Boss Drives 37 EFI with 31 hours on it. It just started giving me problems a couple hours ago. What I'm experiencing is that the motor will shut down about mid throttle and around 3000 RPM. Sometimes it will in idle as well. If I let off the throttle quick enough the engine will idle back down but it has a rough idle after the occurrence. I have changed spark plugs and fuel filters, checked the valve lash, and checked oil. I don't know what to do next has any one got any answers?
