Re: Valve Adjustment
A quick way to tell if the valves being adjusted are completely down and the piston is at TDC of the compression stroke is to watch the valves of the cylinder 180 degrees opposite in the firing order. Rotate the crankshaft back and forth enough to rock the camshaft. The valves for that cylinder will rock back and forth with the cam. Firing order 1 2 4 3. #4 is 180 away from #1 so when you have #1 where you think the piston is at TDC check for valve movement/rocking on #4. The valves on #1 shouldn't move. A good place to start is with the timing pin inserted into the dimple in the cam gear and look through the spark plug hole to observe the top of the piston. That puts #1 at TDC on the compression stroke.
