Is anyone familiar with these engines? I'd really like to know what to
set the brass screw at on the carbs! I've checked the plugs after each
run and they're tan with a little oil residue on the metal, is that
ok? With all the rebuild and cleaning I've done, I just want to make
sure it's not running lean. It sounds smooth and quiet and I can get
the tach to about 5.5 at WOT.
