I have a Kohler 398 cc gas engine (model CV14T Spec 1412)

Customer Question

I have a Kohler 398 cc gas engine (model CV14T Spec 1412) that idles rough and back fires through the carburetor and dies when I try to accelerate. Same problem as "Ed". I check compression, 55 psi and held steady like a rock. Embarassingly, I had to add quite a bit of oil this morning......mea culpa. It ran ok, not great after warming up, then got hot, lost power, backfired a few times and died.

Check compression again, sounds like you have a stuck valve!
