Yes, there is a way to set all valves in two steps. Turn the engine until
No. 2 cylinder inlet valve starts to open. Now turn slowly an notice No. 1
cylinder exhaust valve will also start to open. Continue cranking until No.
2 cylinder's intake is wide open, and then notice that No. 1 exhaust valve
is also coming to the wide open position. No.1 exhaust valve lags a little
behind No.2 inlet valve ,but turn the crankshaft until both valves are wide
open. With these two valves wide open adjust:
No. 1 cylinder inlet
No. 2 cylinder exhaust
No. 3 cylinder both
No. 5 cylinder inlet
No. 6 cylinder exhaust
Now turn crankshaft one full turn until No. 5 cylinder inlet is observed
to start to open. Lagging behind a little behind will be No. 6 cylinder
exhaust. Continue turning until both are wide open and then adjust:
No. 1 cylinder exhaust
No. 2 cylinder inlet
No. 4 cylinder both
No. 5 cylinder exhaust
No. 6 cylinder inlet
I copied this from a Motors manual or such from the library and tried it
on my 235. It worked great.
