Kawasaki engine surges at full throttle.

It has: -Fresh oil (5w 30) -Fresh gas treated with stabiliser. Runs smooth at idle and at midrange but backfires (afterfires) and surges at full throttle. I tried adjusting the high speed jet screw and that somewhat helped but it still backfires every once in awhile and stills seems to surge (more like the speed oscillates a little).When a Kawasaki engine revving fluctuates, this is known as “surging” and it is a direct result of inconsistent volumes of fuel and air being delivered to the engine’s combustion chamber. The problem will lie with the fuel filter, injectors, lines, or the carburetor. Remember, combustion requires both fuel and oxygen.Surging is always caused by an air : fuel ratio that is too lean to maintain a constant speed. Only 2 ways this can happen 1) carb not supplying enough fuel 2) air entering the engine after the carb venturi tube has added the fuel. To test for the latter, start the engine, hold the governor arm at whatever place to obtain the fastest smooth speed.#briggsstratton #carburetor #howtofix More Videos On Amazon - https://www.amazon.com/shop/influencer-44ec13c3In this video I fixed the trash picked tiller wi...
