    I have a problem with my 61" bobcat zt200. Yesterday it started to stall on me and smoke and at high throttle it would rev low and high and then start to stall and i would have to choke it. I shut it of and let it cool then it wouldnt start. Thank good i was cutting my parents lawn and not a customers. So today I check the plugs and they are good, all the wires seem fine. Well from cranking it the battery was dead so I hooked jumper cable to it. And after alot of cranking and choking it it fired up. So i let it run and it seemed alright. I turned it off and then it wouldnt start again. after alot more cranking it fired up. I ran it and tried to cut my property with it. It was doing ok and then it stalled. . I treid to start it and it smoked and there was a little fire out the exhaust. I took the air filter off and it started up and then stalled on me. I pulled the plug to check for spark and there was none. But it will start after ALOT of cranking. I thought maybe the ignition module was going but i am not sure. Can anyone help me. I know there is gas cause u can smell it. Please help me.

    :blob3: sounds like a bad ignition coil, usually when it gets hot and stalls, and will not start till cooled down, this is a sign of a bad coil. tony

    Sounds like the cylinder head gasket is blown.

    A leakdown test will determine.
