Re: Timing is off

I may not have described things well: the timing strobe now flashes when the timing marks are approaching the pointer. When it ran well, the light flashed when the 7 degree mark was at the pointer. Rotating the distributor clockwise causes the timing marks to move towards the correct position, but the engine gets rougher.
The issue of vacuum leaks at the intake manifold is a challenge! I would think that roughness would be present, but there would be no effect on actual timing(?) I'll have to think of a way to test that. I'll check the (new) points just to be sure they are firmly fixed in position. The pointer is in the same position now as in the past when things ran as expected.
HH56 has confirmed my fears about the way to approach the timing chain, so I'll operate on his and Ross' assumption that a jump is unlikely.
