i have an older bobcat mower, with a kawisaki fb460 (12.5) it starts right up, but i can't get it to run for more then 15- 20 seconds. i was using it last week running perfectly, and it recently (2months back) had a full tune up with fuel lines and carb cleaning/rebuild. i was out of straight gas on my last account of the day, but tried to finish one last house, when the mower quit half-way through. no big deal at the time, finish with the 21's, and get gas tomorrow morning. i went to start it today after topping it off with fresh fuel, and now i can't get it to run right. i was gonna change the plug (its also 2months old), but the mower starts right up, pull after pull. i sprayed carb cleaner in, but still got the same results. if i drop it off at the local dealer, i won't get it bak for weeks, even on a minor issue... hopefully this is minor. any ideas. if i can borrow my brothers camera, with digital video, i can record the more the way its sounds. alittle popping. my camera has no sound.
