MG Car Repair: MG midget timing marks, crank pulley, coat hanger wire


Question
QUESTION: I have a 1967 mk 3 midget and wish to set timing with strobe,I can see the fixed timing marks but cannot see the notch on pulley I have cleaned the pulley but still can't see it. I was viewing it from beneath the car. Can you advise me

ANSWER: Hi Eddie,
Yes the notch in the crank pulley is difficult to see so you need to wash the front pulley and put a dab of white paint on the notch. To more easily locate it, remove #1 plug and put a rod like a coat hanger wire in the plug hole while you hand rotate the engine to get the piston at top dead center. At that time the notch will be lined up with the long pointer. We had to do that often at the dealership even when the cars were new.

Answer
Eddie, Ignition timing should be set static. (not running)
You said you found the fixed pointers on the cover and all you need to do is what I told you to do. Find Top Dead Center (TDC) as I outlined and put a dab of white paint on the pulley as I told you we had to do, opposite the long pointer. If you are going to keep the car, you need to purchase a service manual for it.
Use a test light to set timing or you can use your strobe light but not running. Since you are having trouble identifying your model set the timing to 4 deg BTDC on engine prefix 9CG and 5 deg BTDC on 10CG prefix and 7 deg BTDC on 12CC and 12CE prefix. Plug gap and valve clearance can be the same on all.
