This is a fun thread. Interesting how many of us were into motorcycles. Go karts also, like me, anyone? Any musicians, artists, or photographers also? I did not know or forgot that Puch/Indian 2-stroke with dual pistons. Apparently it did not pan out long term with real advantages. About the foggin oil in aerosol cans, CRC makes a very reasonable outboard fogger too. (cheap but probably not as good as the Corrosion X) It's slick to blast it into the 4-stroke crankcase under pressure. If the piston is at BTC the pressure will force it up to TDC (not on compression stroke) then you know a good amount went in. If you are not going to run that engine for a few weeks or more, set the plane with the cylinder pointing straight down and eventually the oil works it's way past the lifters and clear up into the top end. You know it's there when it starts forming droplets coming completely out past the rocker cover bolts.
