RE: Troubleshooting O.S. 46 problem
Jeff,
OS make some good engines, but people who frequent this forum have seen virtually all of their bugaboos too...
With some of their ABN engines (most notably the first generation .46FX), there were numerous cases of peeling of the nickel off the sleeves...
The bearings seem to need replacement, somewhat more frequently than in other engines...
But, the worst are their manuals... Apparently written by ... their advertising dept. ...
Please read what [link=http://www.os-engines.co.jp/english/line_up/plug/pluindex.htm]OS Japan[/link] say about glow-plugs for air engines...
The manual essentially says you can use the A3 for the OS.91FX, while OS Japan says specifically that the A5 is the only one - a two grades colder glow-plug.
The manual cannot be right!
As far as plugs and break-in go, this manual belongs in the garbage, rather than in your library...[:'(]
