Can someone please confirm firing order 90 1275 non cooper s. SparK plug closest to radiator is # 1 the next to the left , further away from the rad is #3 then 4 and farthest away from rad is # 2? I am getting frustrated installing a 123 dizzy. My helper removed old dizzy and cap plus wires without noting correct position or timing rotor location. Thanks.

I have been working on the car and when I follow instructions, have #1 at TDC , slide the dizzy , the rotor is in the 10- 11 o'clock position. If I replace with old dizzy rotor is in 2 o'clock position . It is almost as I have to reposition the drive on the bottom of the distributor. Could this be the case? I would have thought a mini specific part number dizzy would have been correct unless there is a diffrence between the 850,1000,and 1257 .thanks for your help

Sounds like the drive in the block might need moving over a tooth. as per the info in your Haynes manual.

as the drive rotates as it is fitted it can take a couple of goes till you get the rotor correct when you fit the dizzy.

Thank you all for the help. Nicklouse hit the problem on the head. I moved the drive over a tooth and everything fell into place. Started right up and had initial dynamic timing of 14, I backed it off to 10 as per instructions. My curve stated 20 degrees at 2000, checked that and was right on. Thanks again.
