Starter on my Ultra(about 800 hours) --only worked occasionally. Removed it easily (2 bolts, somewhat hidden, removed gas line for clearance). I tried to buy new brushes for the motor, or maybe a new "end cap" which includes the brushes. cheap fix. But I could not find which exact part would match. Gave up. This broke my heart--I had to call Permagreen and order the whole starter motor--$95.00. Kim told me it would arrive next day.
