Valve adjustment.......
People make so much about adjusting them as the old Chilton manuals said to do it(I believe this was the factory specified way too) like their afraid of them. Just fire it up, crank the idle as low as it'll go and still run, and go at it. I've done many of them like that over the years. I haven't done my current one yet but I haven't even started it in over a year. It was set "close" while on the engine stand, dropped in warmed up and broken in, and that's where it sits. The next time I get a chance to drop a battery in and fire it up, that's exactly my next step. Warm it up, pull the cover, restart the engine and adjust em up. There's not much to it.
