    I have a 12.5hp Kawasaki engine that is hard to start when it's cold out. In the summer it starts fine. However in the fall it won't start cold. I can use a heat gun as an engine block heater and once the engine is warmed up it starts on the second pull. Any one else have a problem like this before?

    make sure your choke is fully closed when applied.

    Had one several years back, and khouse is right. First make sure the choke plate is COPLETELY closed or it will be very difficult to start. Choke plate on mine had 2 holes in it, you can help things by plugging one with a pop rivet or a small screw/bolt (if only one hole don't plug it). After that stuff; when starting - try cranking for 5 seconds, wait 10, crank 5. Repeat until it starts.

    I have found that on the kawasakis that if you do not keep the valve lash or clearence adjusted they become increasingly hard to start.

    For it to start fairly effortlessly with some starting fluid. This leads me to believe it would be the carb? What are your thoufhts? Thanks

    Kawasakis are super cold blooded, I have the same problem, electric start is by far better.

    As far has adjusting the valves mabey someone can link us to a thred, or help us out a little.

    Good to know I'm not alone it has been hitting low 30s and not much warmer then that when I start in the morning.

    I have 4 mowers with Kawasaki engines and everyone of them is cold blooded. The electric start ones will start but have to warm up a couple of minutes before engaging the blades,
