I don't think you understand - as there's only compression on the compression stroke, which you can feel with your finger, then bring up the timing markes on TDC, (only turn forward to get TDC - shouldn't have to go very far) then set the distributor so the rotor points in the direction to the #1 plug wire in cap (probably will point between #1 & #4) - Forget about the numbers 6 and 8 inside the cap.

If the distributor cannot be turned once in place because it has a tab that stops it from rotating - this means the timing is controlled by the camshaft sensor and the on-board computer on this particular engine.

As has been said, if the gas is a year old it probably has gone bad. Does it smell like turpentine? If so, disconnect the fuel filter line, connect a fused 12V wire to the fuel pump jumper wire and pump out the old gas and refill with at least 10 gallon of new gas.

If setting for a year you also need to replace the fuel filter.
