Bad timing
I just bought my first goldwing, 76 gl 1000. It ran but not well, it knocked and pinged and has a hight idel,2800 rpm. I checked the timing belts to find out the left belt was one tooth off. Fixed that,then ajusted the valve tapits, and then I cheked my points cleened and gaped, but this is my problem, I sarted to static time the bike whith a lite hooked to the point spring and ground, my light comes on at the full advance mark before the F mark on both sets of points. Is my advance stuck on full? or did someone move the crank puly at some time in its life when they changed the belts ? Or did I over look something.

Re: Bad timing
You should remove the point baseplate and clean and lube the mechanical advance mechanism.
Then set the point gap for F1
Adjust the base plate for proper timing
Adjust the second point gap for proper timing.Do not move the base plate.
This is BY THE BOOK
Now the tricky part.....Measure each point gap.You will find that (most likley)they are different.
remember, to time the F2 mark,it is done by adjusting the point gap,not moving the base plate.
When you get the measurements.Split the difference and re-adjust both points exactly to that measurement.
You will have to move the baseplate a bit to re-time it.
The final should be....points open on each mark AND have the same gap(for dwell angle).
Example...After the first go-around..you measure the gaps at 0.14" and the other points at 0.18"...You would split the difference and adjust both to 0.16" and reset the timing without adjusting the gap again.
Then set the point gap for F1
Adjust the base plate for proper timing
Adjust the second point gap for proper timing.Do not move the base plate.
