Now that I think about it, it was probably before the pandemic. 🤔
Nah, most push and riding mowers are definitely 4 stroke. You’re absolutely correct that 2 strokes need to burn oil and create some visible smoke (to be properly lubricated). Only small, powered equipment (such as trimmers, blowers, and chainsaws) are still commonly made with 2 strokes. My smoking push mower was made in the mid 1980’s and is miraculously still running. It apparently has worn seals that are allowing crankcase oil into the combustion chamber.
Cool, did not know that! I have to admit I made assumptions there, figuring 2 stroke engines are probably more appropriate for smaller equipment. But I guess since you don’t have to carry a mower, a heavier engine is not a big deal, makes sense.
Good luck with your mower, no need for something else as long as it’s still working! After all, with a lot of things they really don’t make em like they used to, that old mower could serve you for a very long time.
