I had to take my exmark 12.5 hp kawi into the shop yesterday. It sat for 7 days because of rain. All my other mowers sat beside it. I go to crank it and put it on the trailer and nothing happens. I decided to wait until later and got the Lazer HP and the encore and took off for some leaf jobs. That evening I tried again, it cranked and ran really bad for about 5 seconds. Then the crankcase vent poured gas and oil into the carb. I took it to the shop and they drained about 1 gal of gas from the crankcase. They said its because "I" didn't shut off the inline valve. Well, the 14 hp kawi sat beside it without a problem. Matter of fact, it sat there for about 2 weeks. Because I didn't shut the fuel off they don't want to warrenty it. For the fuel to get thru like that the float must have been stuck, that is the only thing I can think of why the fuel would have poured thru the carb. What do you guys do?
