I am not smart enough to do internal assessment but I think that is my problem. I have super clean air filters and no loose connections at coils or water near plugs.
Does engine rebuild work out very often or is a multi thousand dollar repair? The dealer cannot look at if for two weeks. I’m on a bad way wondering. Thanks for any and all comments
I understand your hesitance.
Back 40 years ago, as a beginner mechanic, I would have changed the plugs and the wires for just a couple of bucks.
The reason I keep thinking about the plugs is that the engine service manual actually calls out the plugs as a reason for the muffler to overheat. You mentioned that you haven't changed the plugs, so it seems like a reasonable place to start.
However, Tomplum is right that there might be something more serious going on.
I would think it should be repairable, but that will take a little more than a high school kid mechanic to do it.
Was it more like a light switch turning off? Like were you mowing fine and then all of the sudden - boom - all of the power dropped out and it was running bad? That would point to more of a serious problem like valves and head gaskets and the like. If so, I would just call the dealer and pay the price. Yes those problems are expensive and with inflation like it is, who knows.
If you take it to the dealer, you should have them quote you on a full service while it is in there, like a full radiator flush and refill, hydraulic fluid service, etc. Yes that will be even more money but cheaper in the long run.
