I found out it was the unloader. It was 90.00 from Cat. I also bought a pump rebuild kit for 30.00. I will have it rebuilt on the next rainy day. Cost is 40.00.
I can't say enough about the engine though. Honda small engines are awesome. I've just changed the oil, plug, and some Seafoam in the gas once a year for 6 years now. Not one single problem!
