The gaskets weren't the only problem. My first problem was a scored cylinder at 120 hours (warranty and 2 weeks down) I got rid of it with 2 1/2 years and only 650 hours or so on it.
Kohler has all kinds of trouble with this and it is different for some mowers. The 25 has the coils down low, in the Walker that requires the motor to be pulled to change them. More shop time , more expense. Kohler had design problems with the coils too. Ya mine went bad too. The 26 has the coils mounted up top in the open. I can change them now. The head gasket blew (2 weeks down) the intake gasket blew (1 week down). And MY gasket blew.
So apart from bad SAM's,head gaskets, intake gaskets, backfiring, bad coils, bad service, poor gas consumption, poor design, denial form Kohler that there is more than 1 problem with the motor and turfquip being mad at me for trashing the 25's - its a good motor!
Sorry - Post traumatic stress disorder - kicked in. I'm better now.
