Ok so weird thing…just now was able to mow my complete lawn non stop! It’s much cooler today too, but the engine still gets hot.

My first thought is trash in the fuel tank. Might flush it out like new. Blow out with compressed air confirming she is spotless. As Bertsmobile1 said, there is clean and there is CLEAN.

New fuel lines might be called for. They deteriorate internally and can block flow. Probably a new fuel filter while you are there. Freshen up the ol' girl.

Awesome! Just figured out how to pull off the cover, so that’s something I’ll look into!

And clean the cooling fins and block like a new one.

Any suggestions on what to use to clean them? I have something called “purple power” that’s basically a degreaser…would that work?

Now I just need to find the heat shield…figuring once I remove the cover it should be near the muffler?

Brush off the bulk. Compressed air, scrub brushes and degreaser as you like. You will see ribbed cooling fins that need cleaned. Search youtube on cleaning mower cooling fins. Lots of videos on this critical yearly maintenance step. This is for ALL small engines that are air cooled. Trimmers, blowers and mowers..... Clean the engine block like new. Below is a youtube link giving you an idea.
