I only use wd 40 around the bearings after cleaning the engine. I try not too get any wd 40 in the carb cause I heard it messes up the o rings.

I don't touch WD-40 for storing or after run. That stuff gums up plastic and rubber. I use after run oil, Slick 50, miltec or Breakfree gun lube. MMO works great also. Just like most of us in here, I don't after run lube my motors. My cars and trucks at too busy! The end of the season is when I break them down and lube them up for storage.

It depends what engines .... high end engines usually has silicone ( orange or red ) putty inside crankshaft, and WD40 will kill it. Rubber O rings inside carburator also at risk of being swollen.

Use high quality after run oils ( clear type ) even your engine is low end type. Mugen maintenance oil, Novarossi, JP are clear type - high quality oils.

WD-40 is a silicone based lubricant, it works great as after run oil and it displace moisture. but, you should not use it if your crank shaft is silicone putty filled, it will dissolve the putty.
