OSMG0352   O.S.   BGX-1 3500 w/Remote Needle Valve

TECH NOTES
   This BGX-1 is the engine of choice for those Giant Scale Modelers. The BGX-1
35cc Engine was designed as a lighter, more powerful, less vibration, and more
compact alternative to the converted chainsaw gasoline engines. The one
drawback is that fuel economy is better with the chainsaw engines, and fuel is
also cheaper. The BGX-1 includes an engine mount that mounts to the firewall
in the same bolt pattern as the backplate-style engine mounts that come with
the SuperTigre S2000, S2500, and S3000(K) engines. You can directly replace
any of those engines with the BGX-1 without re drilling your firewall.
        This engine is covered under the O.S. 2-YEAR WARRANTY.
