not to change the subject. But what do the dots on the crank gear mean looks like there's one at 9 o'clock /10 o'clock /2 o'clock. which dot would put the cam in at 102* ? thanks for the help.View attachment 1716330431
The lower spocket should have markings to show advancing or retarding the cam,("never go full retard "), but it won't show you what 102° is, you'll need a degree wheel for that.
Btw, is that bottom spocket aa worn as it looks in the picture?
