I had my first problem. The plastic cogs on the starter assembly have worn out and will not engage dogs on the rotor assembly. I have gone to ereplacementparts.com but I am unable to find the part I need. The problem seems to be that the cogs will only engage spring loaded dogs about 3/16 of an inch which causes the edge of the cogs to wear down. I was wondering if I could bend up the spring loaded dogs to engage the cogs farther. See pic for clarification. The saw is still under warranty but I would prefer not to deal with that. Any help would be greatly appreciated thanks in advance. Ray
