Specifications

Once you set up roughly the disc position, you must control and re-adjust precisely the “0°”

of the disc. Then, you will turn the crankshaft in order to move down the piston 2 mm on

each side of the TDC (Before and After Top Dead Center). Meanwhile, each time, be aware

the crankshaft should be driven clockwise (usual crankshaft direction) to clear out all

back clearance from a counter-clockwise rotation. This remark is particularly important more

specially during camshaft setting. In this case, we suggest driving backward (counter-

clockwise) so that the piston goes down a minimum of 3mm (Direction A on the picture

next page). Then, you may run again the crankshaft clockwise to clear out back clearance

(direction B and C on the picture next page).
