New OS46 FX ...difficult to start !
I'd like to add that the 46FX should be started with a very low throttle setting (especially with an electric starter). For mine, I can leave my throttle at idle and she starts usually on first zip of starter. If I accidentally have the throttle open 1/4 or more and try to start she floods, easily, sometimes requiring that I take out the plug and dry'er out. Good luck.
