O.S. Speed B21 RD2 Carburetor Settings and Updated Cooling Head

[@cbh148]

I wanna get one of these engines. O.S. engines have such a stellar reputation, and somehow I still haven't owned/experienced a 21J carb yet. Always heard that carb is the truth though.

Pick one up when you get the chance dude! Undoubtably one of, if not, the best engine manufacturer you could possibly go with.

Hello great video information Adam

[@a2rc]

Nice Vid 🩷 - Is there a way to know if an unboxed engine is the new or old head style (no clear coat vs org)? Thanks for the help

[@nighthawkj30A4]

I run a OS Max .21 TM engine i thought that was the best one. So many different O.S engines.
