7.Tap the end bracket with the mallet as nec- essary to position it. Tighten the bolts to 22 - 25 ft lbs. Alternate tightening in order to pull the assembly together evenly. As you tighten, look through the brush hous- ing access door and watch the bearing to judge end bracket movement and align- ment.
8.Check the
.010 feeler gauge. The measurement is taken through the brush holder access door; see Figure F.24. Turn the engine with the recoil starter rope slightly so that the rotor "iron" is up to take the measurement. (The rotor has two flat sides, which are not measured for air gap.) Slide in the gauge. Then rotate the shaft 180 degrees and measure again. If the gauge does not clear, loosen the four end bracket
