1963 IIA: I changed the points and condenser and reset the timing to 6 BTDC. On the test drive I noticed a ticking noise under load at 30 - 45 mph. Thinking it may be the timing, I brought it home and went to 4 BTDC and still hear the noise. Maybe it is totally unrelated to timing....maybe not. Anyone have any thoughts? It sounds like a quiet rattle snake in the firewall (but here in the Northeast, that wouldn't literally happen). Thanks!
