She runs smooth purrs like a kitten but when you throttle up over 3k RPM's it dies. No sputtering...just dies. The primer wont hold a prime at this point,
Also, after running about 15 minutes I get a long beep then it goes off. Not over heating. Pissing good stream. Changed everything all new plugs ...
