    KAWASAKI ENGINE PROBLEM

    I HAVE ZTR WITH A KAWAI 25 HP FH 721V

    I shut the engine down as usual. did not turn the gas valve off. i never do. next day i go to start and the engine just spins over and i saw what looked like water blow out the exhaust. the previous day i was in a heavy down pour so i was wondering how water got into the exhaust. then I thought no that must be gas. sure enough, when i checked the oil I found that the crankcase was filled with gas.

    How did this happen and what do i do about it?

    Welcome to the new world of ethanol enhanced fuel. Your float needle and seat will need to be replaced. This is a constant battle all home owners and service tech's are fighting. Today's ethanol fuels are causing the needles to not set properly and the fuel does not shut off the fuel in the carb, and the fuel goes everywhere. In your case it filled the crankcase. After you replace the needle and seat you will also have to change the oil. We suggest to all our customers to use high octane non ethanol fuel in all there small engines to try to stop this problem. Good Luck, should be a simple but unnecessary fix.

    Also, do u transport ur mower around on a trailer? If so u should shut ur fuel valve off before u travel because the float will bounce during travel causing this to happen.
