Kohler CV730 fuel delivery issues

+1 on what @Auto Doc's said.
I just recently had an instant shut down on my Gravely. It has the Kohler ZT740 Confidant. It would try to fire but never would. I got it towed around to my garage and took the bumper assembly off for a look. I was checking around the carburetor and the hot wire to the carburetor solenoid fell down. The connection was broken. New connections and some 14ga. Wire fixed it right up.
Take a look at the hot wire going from the solenoid to the wiring harness.
I had already pulled the plunger out of the solenoid while testing for fuel delivery issues.
 
Ummm, Ummm, dirt, grass and grit sticks and collects to greases and oils. Again your mower but clean and tight is best.

Tight is part of the recipe. How about clean and corrosion free? Clean to bare metal polished with Flitz Metal Polish? Use some star grounding washers.......

Take an INSULATED small stick of some kind. Something you won't get shocked with. Tap all around every wire AND connection on the mower. See if she stumbles or tries to die.

Use a finger or screwdriver to push in on all the safety switches. Should kill the engine until you release or press it. Depends if it is a NO or NC connection. A multimeter test on all switches would be good as well.
I will try the insulated stick trick. I noticed it would cut out with or without mower engaged. Thanks.

I started it up and shook every wire and connector. nothing happened . ?? It's been raining here all day, I'll ride it tomorrow and heat it up to see if that matters.
 
Yes, I did clean the tank. That old Craftsman had never had the body lifted off...lots of rusty bolts. About my latest issue of hitting a bump and cutting out/loose connection...I tried the seat switch, checked all connectors on harness, die electric greased, grounds are tight, no bare wire found. Any suggestions ?
Did you remove the tank and actually clean it out? If so, are you refilling from a questionable gas can that has debris in the bottom of it.
 
He did say he cleaned the tank. I didn't see him say he removed it. He started with fuel issues, worked on that, and then said that it stalls when hitting a bump.
I wonder how much the OP weighs? Coming off the seat will definitely stall the mower out.

Yes, I removed the tank and washed it out with some old gas I had, then blew it out. I have no idea what type of gas can the owners are using.

I said insulated stick. Really meant to say fondle the entire harness in a safe manor with the engine on. Gloves with hands inside bend and twist all along each harness. Check for loose fitting connections and such.
