    dizzy/wire? **PICS ADDED**

    I have read and searched and cannot find an answer to this question. Perhaps there is a gap between my reading and comprehension...

    I have a 2.25 pertrol 24v FFR.

    I understand the firing order is 1,3,4,2 and the #1 spark is the valve closet to the radiator.

    My question is this: which wire running from the dizzy corresponds to the appropriate spark plug?

    If you were to number the wires on the dizzy 1-4 and the spark plugs 1-4 what would be the correct sequence from dizzy to sparkplug.

    I'm trying to sort out a timing issue. Thanks for any replies. Have a great Thanksgivng!

      It's whichever wire the rotor points to when the #1 piston is top dead center on the compression stroke.

          I would probably take the distributor cap off leaving on rotor ,take off #1 spark plug and place finger over hole and feel for compression.At this point see where rotor points,it will be close to no.1 wire in cap.

              wires/dizzy

              based upon the responses on my post here are some pics of the rotor, wires and TDC.

              this is what I believe is TDC


              this is the position of the rotor at TDC. the plate is facing south away from the engine/spark plugs


              below are two pics showing the wires from the dizzy to the corresponding spark plugs




              I suspect that the rotor is not positioned correctly assuming I am correct about TDC. Are the wires from the dizzy to the spark correct? Thanks for any replies.

                  It looks like the rotor should be facing 'south-east' at #1 wire. I can't tell which wire is where in the pic but the rotor seems to off of #1 plug by a good margine.

                      Remember the piston comes up twice in the cycle -compression and exhaust.To get it correct,disregard the markings on the crank pulley -place finger over -not inside- the #1 cylinder where the plug goes and feel for compression,not exhaust.Then note the position of the rotor.If it is not pointing close to #1 on cap, and it is like you showed,the distributor could be off by 180 degrees. need to pull out and reinsert. It may affect advance And retard.
