I made the mistake of using an aftermarket air filter on my Honda HRC216. I was just trying to save a few bucks(aren't we all). Well I was mowing today, not knowing what was happening, and all of a sudden engine lost power then died as if I was in real deep wet grass. Checked normal things, throttle control, etc. Looked at oil, looked something like used gear lube, woops. Checked air filter and sure enough dust inside the seal area and down the carb tube. So I ran to the parts store to get some oil (Mobil 1 10W-30). Changed the oil twice to try to get all the dirt out. Now it smokes a little and has a loss of power(RPM) under load. What do you all think? New engine, new mower, will it last this season, anything else I can do? Please Help! Any advice would be helpfull! Thanks!
