Shown here is the E-150 E Gap Tool being used to set rotor position. Then use your timing light to detect point opening. By point gap we mean the maximum distance the contact points separate. Reference the Slick Maintenance manual for complete instructions on setting internal magneto timing.
Slick E gap timing tool(red arrow) inserted into slot in rotor and against poll shoes. Notice how magneto is oriented with the coil up. Locate the appropriate L or R timing slot (shown in lower picture) on the rotor magnet and insert the notched end of the T-150 into the L slot for Left-hand rotation magnetos and the R slot for Right-hand rotation magnetos.
Place tool on Left side for L magnetos and Right side for R magnetos. Rotate the magneto clockwise for Left-hand rotation and counterclockwise for Right-hand rotation magnetos until the T-150 rests against the pole laminations. The magneto is now at the E gap position. Adjust the points to be just opening and you have set inernal magneto timing. Point gap opening should be .008 to .012 inches. Torque adusting screw to18-20 in-lbs. Torque the pivot screw to 15-18 in-lbs. Note: many mechanics do not use this simple tool. They estimate E gap. Comparing this method with the tool shown above you can be off considerably. This may account for differences in rpm drop between magnetos when doing the magneto-check.
