    15 twin Kaw takes 5 to 10 hard pulls to start cold. About 400hrs. on it. Runs, & starts perfectly after the morning cold start. Problem seems to be getting worse. Changed plug. Any other suggestions?

    What are the temps in the morning? Could the oil be to thick due to colder temps?

    Check to see if the choke is closing all the way.

    Temps arn't low enough to thicken oil. I think it's a choke problem but seems to be closing just by looking at the cable. Is there some way of manually priming the engine. If it only happens on a cold start it has to be a choke problem?

    Many of the chokes on Kawis don't close all the way. Push it all the way to choke and then find the metal rod for the choke and see if you can still move it farther. A mechanic at the JD shop told me to slightly bend the rod to make it close all the way. I did it on both my 12.5 and 14 hp kawis and it fixed them both.

    I just hold choke rod shut with 1 hand pull w/ other, throttle about half way. Starts 1st pull 99% of the time. Let off as it fires. I have to install manual choke cables, don't care for chokes combined w/ throttle control

    Before you rush to surgery!

    I had this problem till just a couple of weeks ago.
    Although mine took alot more than 10 measly yanks!LOL

    I started letting the engine cool down for a minute or 2 @ lowest throttle. Then shut off the engine.
    The next day, I pull the throttle up to full choke, give a good pull or 2 and it cranks right up now.

    Worked for me!

    After reading more about what the others have said about making sure the choke is working correctly, I'll havta go back and check mine.

    Good Luck!

    :blob3: i know your engine has limited hours on it but it could also be a valve problem. when pulling the rope slowly can you feel the compression, if so then your ok, but if the rope pulls freely may have a bad valve.T
