OK, I finally started the Slick SB work and had the parts on hand to replace brush and cam on the right mag. Everything seemed to be going OK for the right mag, L rotation. I did the following after pinning the gear to L:
1) removed the distributor block
2) Pulled the small gear
3) Used the E-Gap T150 timing tool to check and reset the timing making sure I used the tool on the L cutout in the rotor, rotating the mag housing clockwise so the T150 stopped against the pole laminations. Then set the points to where they "just opened" using a buzz box.
4) Reassembled, ensuring the large gear was pinned to L and the small gear was alligned to L as well.
5) Re-assembled the cover and installed on the engine
6) Finally, checked that the mag was timing at 25 BTDC.
After re-installing p-lead, groung, plugs and ingition harness, I did a test run. The left mag, which I hadn't touched ran normally, but the one I did, ran very rough. It runs but it's really rough. I re-checked the mag timing and it appears fine.
I'm thinking I've honked up the internal timing somehow. Any clues?
Thanks.
