Honda Harmony HRR 216 Erratic engine operation

bushyiiiApril 16, 2012

The engine continually changes RPM, it is as if I were gunning the motor. It goes from a slow idle up to a fast rev and back down. Any ideas?

Bad fuel, namely drops of water passing through the carb.

Turned out it was a plugged gas cap. With the cap off the engine ran fine. It must allow air into the tank somehow.

I cleaned out the cap real well and now it seems to work without the engine hunting, revving up and down. Hope this helps someone else as well.
