    I have 3 walk behind mowers all with the Kawasaki FH541V KAI 17 hp engine. 2 of the engines start on first pull everytime. The 3rd one takes 5-6 to start in the mornings and after it sits for an hour or so and cools down. I've tried choking and not choking and both are same. The only difference with the engine that doesn't start as easily is that it hasn't been used as much. The 2 engines that start well we use almost everyday. The engine that doesn't start well only gets used about once every 10 days or so. I've replaced the spark plugs but the old ones looked fine. The engine that is hard to start only has 20 hours or so on it but it is 2 years old.

    Please help.

    I would run some seafoam through it to clean the fuel system and carb if it has only been used 20 hours in 2 years, could be a little gunked up.

    Thanks Jhawk. How do you do it? Just pour that stuff into the gas and oil?

    Put it in the gas to clean the fuel system. I've used it with good effect. I have not used it for the oil yet, but I think I may put some in my WB before the next oil change.

    I had a thread on here last week asking about a Kawasaki engine that was hard to start. I put some seafoam in the engine and ran it for a little while but still need to run the gas out of the mower to run all of the seafoam through. I went out to start and run again this morning and now the string pull won't even pull out at all. I ran and mowed with the mower just last night and it ran beautifully. Has anyone had this type of problem and what was the cure? I'm calling the dealer tomorrow concerning warranty but thought I'd get an idea of what it is before I talk to him. Any input would be greatly appreciated. The mower literally has 25 to 30 hours max on it. I have 2 other exact same engines with a bunch more hours than this one that start and run flawlessly. Its a kawasaki KAI series 17hp twin V engine.

    Thanks in advance

    Sounds like there is a possibility you bought a lemon, hope not!

    Pull the spark plugs and see it it turns. If it does, your carb leaked fuel into the cylinders. That's about all I can think of. Tony

    If I drop Coleman lighter fluid and Isopropyl rubbing alcohol in my gas tank, do you think it will hurt the engine?

    Because that's what's inside that bottle of Seafoam, and it probably didn't hurt the engine, but I also don't think it helped it any.
