I just finished my 30k service, and the timing and carbs were set up tonight. It idles pretty good, but the 5-6 carb is making an intermittent spitting/ticking kind of noise. It's not constant, and only happens at idle. I drove it around the block to make sure everything was OK, an only heard the noise at idle. Note that the air cleaner assemble is not back on yet. It was easier to adjust things with it off. Also, I wished I'd know about the Exxon Valdez effect on my garage floor when the dist. are and you're setting the timing. Ugg, what a mess that was.
