I'm so pleased with this I had to share. Took my k3 off the road for a couple of weeks to do a few odd jobs, over 18 months later I've just finished it. Not intending to leave it that long I did no up front prep, a couple of months in I added fuel stabiliser, in November I filled carbs with redex. Yesterday with nothing more than a new battery and draining the carbs it started literally on the button - no cranking, just near instant firing on all cylinders and a smooth tickover.
