Hello,
I've searched this forum and the internet and have not found my answer yet. My bike is running Pamco, E-Advancer, PMA, Normal Battery. It's a '73. I've been slowly tuning it up to sell it. When I got it, it had a standard ignition/points. Before doing anything, I followed the advice of: Adjust valves, timing chain, points gap, etc... There were no timing marks on the PMA, so I removed the valve covers and used a TDC tool to find TDC and that correlated with the camshaft pins, etc... I then marked TDC to check timing. I used both a test lightbulb and a strobe light and saw that the engine was firing approx. 30 degrees beyond what I'd found to be normal timing position. I've added a Pamco with E-Advancer and still see the same firing position. When revved up, the timing advances as it should. It runs ok and does not kick back or seem to be running as it's indicated. I'm going to re-check my timing marks again.
A stretched cam chain would retard timing, correct? I thought about a skipped tooth on the cam chain, but the cam position matches piston @ TDC when I checked.
A big thank you to this forum for all the help I've already found through reading here.
Any ideas?
