Do they rust over if the engine sits unused for a period of time or not really?
If it's humid and the intake/exhaust valve is open, yes. Especially on small engines where water can get inside easily.
Yes your fine.Does it take a while or not really? Say it sits unused for a couple weeks, is that fine?
My brother has rebuilt several hundreds of lawn mower engines for probably fifty years now. A little less than two years ago he started a business in Florida repairing and selling used OPE, they find or get from people. It is very rare according to him to find rusted cylinder walls, even in engines that sat for very long periods of time. Many cylinder walls still have hatch marks which hold oil. If the machine is well maintained you have nothing to worry about imo.Do they rust over if the engine sits unused for a period of time or not really?

Yes, to clarify B&S and other sleeved engines used on commercial mowers, lawn tractors, generators etc. Iron Duke used in boats, along with Chevy 250 I6 and Chevy 350 V8 engines as well, he has torn many engines down over the years. Rusted cylinder walls are a rarity unless they sat out in the open with plugs out, an open carburetor etc.Most mower engines are aluminum bores unless commercial grade
Well that's good. I always wondered about my pressure washer that only gets started once every 6 months or so. Maybe I'll stick it back out in the shop with no hvac.Yes, to clarify B&S and other sleeved engines used on commercial mowers, lawn tractors, generators etc. Iron Duke used in boats, along with Chevy 250 I6 and Chevy 350 V8 engines as well, he has torn many engines down over the years.

If you're concerned, you could add a little TCW3 to the gas.Well that's good. I always wondered about my pressure washer that only gets started once every 6 months or so. Maybe I'll stick it back out in the shop with no hvac.
It takes some time for that to happen when a valve remains open and it is stored in a moist environment.. If you plan on storing, fogging oil will prevent rust from forming for a long time.Do they rust over if the engine sits unused for a period of time or not really?
We do have very foggy days in the winter where everything has moisture on it even inside a garage unless it's heated. I always wondered if the engine of the engine was the same way.It takes some time for that to happen when a valve remains open and it is stored in a moist environment..
