Tighten dizzy bolts

If Im missing something, someone chime in.
The dizzy bolts are 12mm I believe.

The timing marks are difficult to see at first, there will be two pointers that you will have to line up with your eyes (one eye is easier). (IIRC)There will be 4 marks, TDC 10 20 30. The pointers are below the cam gears, and above the crank pulley. The timing marks will be on the crank pully itself, just point and shoot. It would be best to get a dial in timing light, they're about 60 bucks. Use and return. When hooking up the timing light, the clip wire goes onto #1 cyl (nearest the cam gears) and to the batery for power.
