I finally got my LO206 where I want it in terms of idle, acceleration and top speed. However when I start it up it sits between 2k and 2,200rpm which is fine, but once I hit the track and get up to speed I take my foot off the throttle and the engine only pulls back and stays at 3800 RPM.....so I'm breaking to slow down, but it keeps going back up. On top of that there is a corner I like to slow down in and I go to back off and not only won't it back down it accelerates back up to 4,100 RPM....So I let coast on 3800 RPM and eventually it slowly drops down back to the correct Idle speed of 2,200rpm. I have tried everything and I can't figure it out.....when you take your foot off the throttle, the throttle cable goes loose like it should so I have no idea whats going on......any suggestions would be helpful. When I pull in to stop it's sitting at 3200 rpm and I have to hold the break down while I'm shutting down the engine which is burning up the clutch...very strange
