Re: Force 85 HP 1988 Spark Gap & Idle Speed
These engines run Gapless plugs (Champ #UL18V, Rfi plug is #QL76V).<br />The idle can be adjusted at the cam on the side of the lower carb. Remove the throttle cable, unscrew it a few windings,and re-atach it. The other carbs will track the same,single adjustment.<br />.
