Im not ready to give up on my YS.63 just yet. But I have had problems keeping it running consistantly though. Im thinking its the fuel Im burning so Im going to try another brand. The funny thing is that most of my engines seem harder to keep consistant since Ive been using this brand.....even my two strokes. So until I try this I'll keep it.

I mean when its running its honkin big time....hauling around my 5.5lb Flip with authority, but when it gives up it just gives up. It's almost like it starts to run lean at the most inoportune time. Like at 4' TR'ing on the deck which is where it let me down last time. We shall see though.
