Sorry if I wasn’t clear in my explanation . The engine is running fine in my opinion, but the implements (54”mower, 47”snowblower) are what is bogging down under load. I just changed the plugs and cleaned the air filter, this past fall. I haven’t found a fuel filter but will have a better look and change it. I have a tach to check rpm, to make sure it’s reving to max.Thanks for your advice!Do this. It will run fine but with a load you need to supply the engine with more air and fuel.
If what you state (the engine bogging down) I wouldnt be looking at a hydraulic issue. Fuel and air lacking will cause a loaded engine to bog.
