went and looked at this 743b bobcat . started fine, everything functioned as it should. no oil leaks. so guy delivers it. starts right up, unloaded it and drove it to the canopy by the barn. I am completely new to bobcat. next morning went to start it. no go. not even a puff of smoke. turns over fine. did notice fuel gage was low so I added 5 gal of diesel. venedt the fuel filter and it was full. primed the bulb up till is was hard, start. I manually opened the shut off valve which I think is air but still no start. so if anyone can steer me in the right direction I would appreciate it. I had the bar all the way down when I tried to start. thanks for reading, norm
