This is an odd one. I posted earlier about trying to tune my 68' 318 due to some poor hot idle performance and occasional stalls.
I decided to get the timing right first before going crazy with the carb.
With vac advance connected, at idle, I'm at 800rpm and approx 10* BTC.
With vac advance disconnected, I'm at 250rpm and I can't see the timing mark - it just disappears (I have marked it with a bright white grease pencil to make it clear and bright). Not sure if it is on the opposite side of the wheel, or if the rpms are too low to register. I tried adjusting the timing to bring the mark into view and didn't have any luck despite turning the distributor significantly.
I checked that the mark on the wheel matched actual TDC, thinking maybe the chain slipped or something and the TDC marker on the wheel is right where it should be.
What does this mean? I've got an electronic ignition that I want to put in there, but if TDC is nowhere to be found I'm hesitant to go messing with it.
Thanks for the advice.
