With the engine at #1 TDC (firing), you can adjust both valves for the #1 cylinder. Then rotate the crankshaft 120 degrees in the normal direction of rotation (CCW looking at the flywheel end) and you can adjust the valves of the next cylinder in the firing order and so on until you have done them all. Too tighter valve clearance & the valves will hold open, they may burn & the engine will run rough, the engine will lose compression. If the valve train is not damages, and only out of adjustment to the point that it tics, you may see a difference on a dynamometer.Adjustment: The fuel injection timing depends on the fuel pump lead.
