First, with spark plugs out, rotate the engine until the number 1 cylinder is at top dead center (TDC). Tighten the valve until only slight pressure takes up all slack. Then turn the adjustment nut 1/2 turn. Do the same for both valves. Now, rotate the engine 90 degrees, 1/4 turn of the crankshaft. Following the firing order, 1-8-... adjust each valve as you did for the number 1 cylinder. By grounding the number 1 plug with a wire attached to the engine, turning the distributor clockwise, and then turning on the ignition key, you can then slowly rotate the distributor countrclockwise until the spark plug fires. This should set the timing enough to start a freshly adjusted engine. Good luck!!

To set the engine idle for a 350 engine, first, ensure the engine is at normal operating temperature. Then, locate the idle adjustment screw on the carburetor or throttle body and turn it to increase or decrease the idle speed as needed. Typically, the idle speed should be between 600 and 800 RPM for a 350 engine, but consult the owner's manual for specific recommendations. Finally, recheck the idle speed after adjustments and make sure the engine runs smoothly without stalling.
