Question about Craftsman 21 hp 42 in. Deck Yard Tractor - CA Model

Intek engine runs poorly under load and when warm

I have a 42" Craftsman mower with a 21hp Intek engine. It starts normally and runs great for the first 5 minutes. Then under load it starts missing terribly. Spark looks ok, pulling the choke out half way seems to help smooth smooth the engine but with strong unburned fuel smell. Any suggestions?

If it's carbureted, make sure the bowl float isn't stuck.
Another possible idea, and not saying that this is it, but many small engines have a small sensor that will hour allow an engine to run without having an adequate oil level.

If it is a V twin Kohler engine, you may have a blown head gasket. It is a common issue. Great engine but has this one issue. Kohler has a head gasket kit with improved head bolts. Torque specs are included. You will need a inch pound torque wrench and common hand tools.

I have a craftsman mower with the B&S 21hp Intek OHV motor, it starts fine but when you go to engage the blade or go forward or backward or release the parking brake it will die unless you disengage...


Check the switch on the seat, of all places. There's a safety switch on the seat that will kill the engine if it's not engaged when do anything other than start and run the engine.

If the switch checks out, get back with me.

Sounds to me as tho it might need a carburetor adjustment, providing there is an adjustment screw on the carb. Sounds like the engine is running a bit lean. Did this problem occur right after the carb cleaning, or was it there in advance? Is there a fuel filter that might be clogged?
