Hey i have an os .18cvr w/pull start on my rc10gt. I broke it in according to the instructions and it ran great. One day i wasn't paying attention when i was hot lapping it,and before i knew, it was running at 275 degrees. I immidiately cooled it off and hoped for the best. When i tried to resart my truck but the pull start would just pull freely not catching the shaft. I removed the pullstart and cleaned the one way bearing and tried it again and it worked like a champ. Now every time i run this thing i have to clean the bearing out to get it to pull. I went ahead and replaced the rear adapter plate and the stater shaft thinking that would fix it but i'm still having to clean the bearing after every run. What else could be the problem?
