My Idle had dropped to 600, (on the tach ) stalls sometime when shifting between fwd & rev
Seems like just a tad of play on the linkage,
Books calls for 750 (+/- 50)
found the idle screw tucked in on the left side under a black tab cover on the intake manifold
turned it CW about 1/8 turn (used needle nose ) .
will see next time out if I'm back to 700 - 800
