Genny fires then dies

Wildboating

replaced impeller, flushed all pieces out.  Ran good for an hour then shut off, now it fires smoothly then dies 5 seconds later.

#1: plugs.

Ran ok before the impeller? Did it overheat? Plugs and a tune up, did you replace the coupler behind the impeller pump?

possible it got hot when the impeller fried, fouled the plugs.  Notoriously eats sparks plugs.

Same thing just happened to me.   It was a misfire on cyl 1.   Mechanic replaced plugs and now works like a charm

Oddly, after that day it worked itself out.  Seems to be running fine without hesitation now.  I will go ahead and grab a plug though.  Thanks

Takes 2 plugs!

NavyCTRC

buy four, you will need them eventually.

Oh, 2?  Thanks for the heads up!!

Yes. It is a V-twin cylinder Kawasaki engine. 

NGK BPR-4ES. They are long nosed plugs. Do not use the engine info to find plugs, it will say to use the short ones. 

These things eat plugs. Even if they look good: replace.
