    What are the engine numbers? That is where the problem is.

    Enter as CV20-65597, it is a good number. Check the fuel line, it may be spongy and collapsing. Als look at the fuel filter.

    As Roy most it is carb related problem.
     
    Check the usual stuff like fuel in bowl for water. Loose electrical connection causing the fuel solenoid to drop due engine vibration. The wiring doesn't show the fuel solenoid wiring circuit but I know it got to be there.
     
    If wish to clean the carburetor the ipl is showing that you have the single barrel Nikki which the repair kit is PN 24 757 18-S. Now Nikki and Kohler are proud of these kits so they are expensive when to other carb kits.

    Found solenoid at bottom of carb / now earlier it started then tried to die then it speed up somewhat and would run with full choke and when I eased choke of it would start to die and then it finally died . Then back to same routine starts runs 5 seconds and dies and will immediately start again

    Drain the tank and add a small amount of isopropyl alcohol to fresh gas.
