126 overheating problems
 

Neighbor has a 126 that shuts down after 15 minutes of cutting . He had a bad exhaust leak blowing into the air cleaner which I thought was the problem . He said he wrapped the leak but said this was not the fix . Any info on this problem would be greatly appreciated . Thanks !! CCS

it might be the coil, ive had a few that would get hot and stop working therefor shutting off the tractor.

The coil was hot for sure as well as everything else on the entire motor . Untouchable ( would take the skin off your finger) . I asked if the 126 had a fan on the driveshaft but he couldn't tell me . I'm just going to pass on any info I can until I can get the tractor back over to the house .

You won't find a fan on the driveshaft of a 126 unless somebody put one there. And if there was a fan, it won't do diddly poo to cool the motor.

Overheating can come from a wide range of problems that a few people will chime in. Among one I'll offer: cooling fins clean behind all tins (tins better be there)!?!

There IS a fan on the Kohler K series motors. It is part of the Flywheel. This information is clearly stated in the Service Manual.

could be.....
plugged cooling fins
plugged grass screen
hi resistance in the plug wire
bad spark plug
low battery voltage
bad connections
faulty coil
faulty condenser
bad points
sticky valve
dirt in fuel tank
dirty fuel filter
dirty carb

hope that narrows it down for you. what have you checked?

Lean condition from an improperly adjusted carb.

Let's see if it's missing a flywheel before Superman goes all that!:ROTF2:

Haven't checked anything yet and by the list of possible causes , I think I'll pass on this one . I no longer have the available/needed time to devote to the neighbors tractors . All good information to pass on to the owner though . He can decide which direction he wants to persue . :Huh:

thought of that after I hit submit reply.
how about ?
excessive carbon buildup causing pre detonation
leaky head gasket causing a lean out
bad gasket between carb and block
