Have a gator HPX twin Kawasaki.Carb is flooding when key is turned on.Took carb apart,float and seat look ok,but plastic,no adjustment.What are the two wires going to the carb for,one on top,and one on the bowl.Not sure why it is flooding,any help?Thanks.

A bit out of the ordinary symptom there, only when the key is turned on? Wire to bowl would be anti-dieseling solenoid, don't know about the 2nd wire on top. I would be looking into the venting system for the fuel tank, sounds like it might be plugged up and the real issue is way too much pressure buildup in there possibly. The little plastic bowl float just can't hold it back. But this really doesn't make sense unless the 2nd wire is controlling a fuel inlet solenoid, would be the first I've heard of one which is why it doesn't make sense to me, but I also don't have hands on experience with this particular system.

When the key is turned on,the electric fuel pump runs,causing the flooding.I've looked everywhere,but I don't know what the wire does on top of the carb.I believe this is a 21 hp Kawasaki.

First thing to do then is measure your fuel pressure and confirm that it's not astronomical due to faulty stuck bypass system. Small engine fuel pressure is modest, something like 3 or 4 PSI is almost too much. If you can't shut it off with your thumb over the open fuel hose, then too much pressure is your problem.

There appears to be heater in the top region, possibly to offset carburetor icing, while the lower connection does go to a fuel shut off solenoid as suspected. Still have a foreign object under your needle seat even after disassembly is about all I got. Change the fuel filter, test for over pressure at this time, clean the carb again blowing backwards thru the needle seat with a can of brake cleaner. Hold the carb upside down and blow with your mouth into the gasoline inlet to test needle, seat, and float that it can shut off low pressure fuel in the first place, you may have a loose seat.

Thanks,I'll try that.

Took it all apart,cleaned it and blew everthing out with compressed air,back together,runs like new.Must have been some dirt in the seat area

That's great, I like it when a plan works out. So many times with carb work like this we don't get to see the exact problem, thank goodness a good clean out is usually the trick.

Thanks Lee,and the best part is,it didn't cost anything to repair.Was able to use the old gaskets over,none of them tore!
