Re: video Champion hot rod

When I was young, I used to play with “Mobylettes”, the small french moped 50cc.
The goal was to improve performance.
This often ended with broken rings, pistons and other damages 🙂

I wonder what would happen if I try the same thing to a cheap outboard engine …
Maybe I should build my 3.6 Firestone as a race engine 🙂

When I run "stock" (cheap) motors on my grandson’s hydroplane that we built together, I double the oil in the gas and so far it’s prevented self-destruction of engines running above their rated RPMs. Note that the gas/oil ratio spec’d by Champion for their class A (4L and 4K) Hotrods was 4 to 1. Maybe the class B Hotrod was also 4 to 1 ?? I also go one heat range colder on the spark plugs. With a Champion stock 4LHD on a hydorplane, I had to go two heat ranges colder to keep the plugs decent.
