Surging Kawasaki Engine

I have a 15hp Kawasaki on a 48 Lesco and the engine surges. I did all the routine things I could think of. Changed oil, air filter, emptied carb bowl, cleaned fins, sprayed carb cleaner, fuel filter. A couple of times it stopped surging when bring it to full throttle. Anyone have any Ideas?

you need to remove the carb and clean it. you need to clean all the jets. Surging is caused from a lack of fuel.

when the fuel was coming out of the jet it was bogging down. I could see the fuel spray then it would bog.

i would put my paycheck it is in the carb. 99.9% of the time surging is caused from lack of fuel. take the carb off and take your time cleaning the jets (all of them) Dont just spray carb cleaner into them. sometimes you will need certain tip screwdriver sizes to get the jets out. just take your time cleaning with carb cleaner and blow the jets and carb out with air. i am sure this will take care of the problem. make sure all gaskets are in good shape. (do not use silcone for gaskets) let me know!!!!!!!!!

I would tend to agree that you have a carb obstruction. After my experience with two Kaws(17 and 23 twins) do not overlook worn governor internal parts wear. In one case the plastic plate that separate the governor balls had badly worn bosses on the back as well as a badly grooved governor plate. In the other case, the bosses had been sheared off causing the engine to over rev. In the latter case, prior to over reving, the customer experience the surging you describe. Just something you may want to consider if the carb cleaning doesn't correct the problem. It would also depend on the number of hours you have on the unit and whether or not you had ever esperienced any low oil situations.

If cleaning the carb as leeker and Dutch mentioned (which I also think so) does not solve the problem check the governor adjustment.
