    I have a 19HP Kawasaki engine on my ZTR, and have had two problems with engine flooding. How can this be prevented? My dealer told me that sometimes flooding can occur when dirt gets into the carb and holds the needle open. He also advised me that when you switch the gas valve (the one that switches draw from either tank) a vaccuum may occur and flood the carb. When switching the draw from tanks, can the engine be running?

    Does anyone know a sure way to prevent flooding? This is most likely the simplest question ever asked...but i'm just not sure! ;)

    dirt in the needle seat is right. i don't agree with the vacuum thing. also make sure the choke fully opens.

    I agree with khouse on dirt or trash, You can switch tanks at any time running or not with no I'll effects on the engine. If you have rough roads around your area it could be flooding from bouncing around on your trailer.
    Shut the fuel off while trailering for a few days and see if that helps.
