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?
