Re: Kohler Courage Engine Very Weak and Popping
BTW, while we are talking about it..what year is that courage single?
They had lots of probs with the front 4-5 bolts loosening up and self destructing the engine.
85%+ of the 04 and earlier I see are loose. Seen 3 06 loose and never any 07+ that were loose.
Always check single courage front top crankcase cover bolts.
If loose, put lock washer or clean and loctite them and torque to spec. I would have to look it up again but its a 8mm and I think the kohler service manual said 216 in lbs.
