Customer Question

Hi
Kawasaki FJ100D, fires and runs for a few seconds, then conks out. Tried all the usual suspects, but don't understand the throttle linkages

Have you checked the flow through the needle valve and float passage?

Expert:  Curtis B. replied 1 year ago.

Linkage is not problem,but not enough fuel getting through the fuel passage.

I'm not that familiar with carburetor anatomy, and haven't resorted to dismantling it. But, there seems to be plenty of fuel in the carburetor, as it drains freely when I release the drain screw.

The needle valve and float control the flow into the bowl.

I've already paid and downloaded the engine manual. But it is technically loaded and the troubleshooting section is rather vague.

Here is a basic, easy ,carburetor breakdown. It is not yours, but all carbs are built alike.

Thanks. I'll give it a try tomorrow, as it's getting late and dark here now.
Expert:  Curtis B. replied 1 year ago.

OK, thanks!

I've detached the carburetor, but I think I've gone beyond the scope of my capabilities. I'll have to take my mower to a repair specialist before I make matters worse. So could I have a £10 refund, please?
