Hi All, For some reason, I can only see the TDC pointer when timing. Possibly the wrong crank shaft pulley? I should be able to see all five points, TDC, 5, 10, 15, and 20; right? Thanks, Mike

The points are welded underneath the and on the timeing chain cover, some have more teats than others. a small v is cut in the pulley.
 
Yes, I know, but looking at the bottom of the pulley from the front, only the TDC is visable. Mike

Well that's a start, surely can wing it from there. Timeing does change a bit as things get worn in any case so the marks are only a place to start.
 
The pointer could have been bent at some point in the thirty-five odd years of history. You ~may~ find taking time to use a screwdriver as a leverage tool and some scrubbing around on your back to do the task worthwhile. That said, I'd be inclined to "memorize" the distance 8 degrees is from the visible TDC mark and "wing it."

Most of my MGB's got a second pointer installed on TOP of the pulley, via a timing cover bolt and a distinct groove in the pulley. Pointer made from a wire coat hanger and "indexed" with dial indicator and degree wheel.

All to eliminate the flopping around like a caught carp. /ubbthreads/images/graemlins/wink.gif
 
Excuse me if I am misunderstanding, but there should only be one mark ON the pulley and the guage marks are on the timing guage attached to the engine...no??? /ubbthreads/images/graemlins/confused.gif

Yep, one mark on pully a cut v in the front part. Guage marks,the teet things, pointers, are on the timeing cover behind the pulley welded on.
