Hi All, I have a 2013 Z915B Kohler CV740 725cc / Spec CV740-3144 Serial # 4310501211 Build Date 4-15-2013. Carb # 24-053-92 / 621030-141-2Z07... 700 hrs. OK with all of that... she starts up runs bout 15-20 mins and stalls….. I did all of the fuel delivery checks, fuel is being pumped to the carb inlet.... so after a cool down of an hour, I pulled the plunger on the shut-off solenoid started it and the same thing.... 15 min run time... stalls out.
I did check the fire at the plugs just after it stalled,, and had spark (although it wasn't as dark blue as I would have thought it should be)..... checked the fuel pump, and it pumped fuel....
Question 1) by removing the plunger, will that eliminate the solenoid getting too hot and failing? Id say yes. btw, the fuel shut off solenoid is the early type 1 wire connection.
2) What other heat sensitive electronics would cause the motor to stop
3) Is Vapor lock common? (There is no heat shield between the muffler or the carb.) I'd say an engineering mistake..
Other notes... No carb work as of yet but no water or dirt in the bowl. fuel lines are original but appear to be tight.
as soon as I figure out how to add a pic.... I will!!!
