Dwell angle: 30 degrees (no gap specs, set with meter)
Timing: 5 ATDC with vac (7 BTDC with no vac)
Valve clearance: 0.08 mm intake, 0.20mm exhaust. You MUST have the special crow-foot wrench for this, a standard one will probably only spread. Note that these are mm, not inches!
Clearance adjustment is a pure pain. Due to the design of the cam followers, you MUST rotate the engine after adjustements and re-check to insure that you didn't just bind the follower on the ball pin.
