Yeah – I want a Champion Class B Hot Rod too, but the couple I’ve seen come up for sale have been over-priced junk. I’d settle for a Sweet 16 too, or the rare Tandem 33 pair! Biggest Champion I’ve been able to get is the 8.4 HP 4LHD Hydro-Drive. I remember drooling over them when I’d go to Swanson Outboard (only 15 miles from me) to get Champion parts around 1980 when Lyle Swanson was still building them up new from the factory parts stock he had. When he sold off the parts and rights to them, he told me he "got tired of arguing with Mercury’s lawyers every time one of his Hotrods won a race"!

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.
