First and IMPORTANT. The adjusting screw 'E' as shown in Figure 17 should always be set so it will just touch the push finger 'G' when the spring arm 'C' is in a horizontal position. If screw 'E' does not touch push finger 'C' or if it is set in too far you will only get a weak spark.

Second. Be sure timing lever 'J' shown in Figure 16 is in running position, then turn the flywheels to the right until the piston starts back into the cylinder on the compression stroke, then continue to turn them slowly until the word Spark on the rim of the flywheel is opposite the top of the cam rod (Figure 18). This is the point at which the spark should be made.

Third. Place the tripping lever 'A' on the magneto and cock the springs as shown.

Fourth. See that the screws (Figure 16) which fasten the clamp to the push rod are tight and that the one nearest the cylinder head is in the hole in the bottom of the cam rod, then adjust the length of push rod 'H' (Figure 16) until the end of the rod touches the push finger 'G.' Tighten locknut '0'.

Fifth. Loosen set screw 'S,' move wedge 'K' on the push rod toward the magneto until the lower edge of the end of the rod 'H' is just even with the upper edge of the magneto push finger 'G' as shown, tighten set screw 'S,' then the locknut 'X.'

Sixth. Take off the tripping lever, be sure the magneto wire is fastened to the terminal . Turn the flywheels to the right to see if the magneto trips off when the word Spark is opposite the top of the cam rod. If not, adjust the wedge 'K' (Figure 16) carefully until it does. To make engine fire earlier, move wedge 'K' toward magneto. To fire later, move wedge 'K' away from magneto.
