Thought I would share how I set the valves on my new-built 235 while it was on a stand, using a "companion cylinder" system. First set #1 cyl TDC compression and check with a straw in the spark plug hole. Then mark the damper at 12:00 for reference. Both #1 cyl valves are now closed. So are #s 2 intake, 3 exhaust, 4 intake and 5 exhaust. I set these .010 for intake and .020 for exhaust. Turn the engine one revolution back to 12:00 on the damper mark and check #6 piston with the straw. Then set both # 6 valves. Next set 5 intake, 4 exhaust, 3 intake and 2 exhaust. Notice in the picture that the column on the left is a mirror image of its companion cylinder in the column on the right. It runs smooth and quiet, cold or hot. I have not had any reason to re-check the valves after 250 miles on the farm and highway. No "ticking." Almost have to hear the exhaust to tell if it's running. Hope this helps someone.
