The cam sprocket with 36 teeth means one tooth jump is 10 degrees.
Before I tore it down I might try shifting the chain around the sprocket enough to get the marks to line up.
With tensioner loose, slide the bearings off one side of the cam, lower cam, work the chain around sprocket one tooth. Lift cam, check marks, repeat till they line up.
tighten the tensioner.
One or two teeth off probably isn't enough for valve to piston contact.
If you get it lined up, try setting the points. If they set then try running it. If it runs ok with no extra noises then run it.
If you have to run the tensioner way in, so the cap barely fits then the chain is stretched.
You can do a complete tear down but why not try adjusting the chain and points, it may be fine.
