So it was the spring loaded grey connector. The spring has pushed through on the inside plastic shorting the seat switch connection wires. This circuit should be open with a rider in the seat.

Thanks for the reply. I cross-connected the pigtail to the seat switch wires with a test wire and the mower still dies every time when I release the brake pedal.

Cranks, starts and idles fine, but as soon as I release the brake the engine dies instantly. I checked seat safety switch which is normally closed-when no rider is on the mower and open when a rider is sitting on the mower. I am looking into the interlock switch now, but not 100% sure on how...

OK, I found out what happened when I put the new belt on 3 times. lol The bolt that goes through the clutching idle pulley and the frame came loose resulting in pulley sag. Due to the sag the belt was riding too low on the stationary idler causing the belt to jump off. I did fail to to put the...

Pulled deck to see...it is obvious my mistake :( and both idlers are fine.

When mowing I can smell slight burning rubber and the brake pedal bounces. This drive belt was replaced about two years ago and is now mostly shredded. Mower is the 917.271022. Any ideas? Maybe an idler pulley? Thanks for help/suggestions.

Here is the final problem. The nipple from a fuel filter broke off inside the last section of fuel line connecting to the carburetor-wasn't me. I had blew air through the lines and observed fuel flow out of the line, so I thought flow was OK. Today I decided to remove and LOOK through every...

If you are running along and the anti-backfire valve loses power the mower continues running? My understanding is the valve closes as soon as engine is turned off blocking off fuel so it does not end up in the exhaust causing the "backfire" as the engine winds down those last few strokes. One...

Seems the ignition switch has been opened before and the internals were put together incorrectly causing a short to the blue wire in all positions except off. Fixed this and I had significant improvement to the longevity with blades engaged, but fuel starvation is still problem. I can mow at...

Has to be something going on inside this engine. Replaced coil due to wire damage and no change. OK I'm desperate so I will try a new spark plug.

Definitely not one fitted on this mower that I can see on the speed control bracket or the air cleaner base according to p.21 of the Kohler service manual. Manual also states, "Some engines are equipped with one of two optional pulse fuel pumps." I am not convinced that this mower should not...

Thanks! I was wondering if it required a fuel pump or not. The service manual only states there are two-types while leaving open the possibility that no fuel pump is also a possibility. Seems I ran across another very similar engine without a fuel pump so I kinda moved-on from the lack of fuel...

Thanks for all the input everyone. I did put a new carb on and the new carb acts exactly like the old carb. To test vapor lock, I setup a floor fan on high to blow heat from the exhaust away from the carb since there is no heat shield on this mower (checked diagram to verify). I let the bowl...

Removed tank, and verified that I do not have any blockage from the fuel tank through rubber line as it connects to the carburetor. Next, I checked the fuel solenoid and it has 13.7-14.0v at WOT when the engine is acting up and cutting out. Moving governor works fine when the engine decides to...

Blade engagement is mechanical. :)
