OK, So I may not supply quite enough info for a complete evaluation but, I am going to try and get your alls advise.
Yesterday when I went to rotate to take off, just at or before the nose gear lifted, I felt a pretty significant shimmy in the nose gear. The nose came up and the airplane lifted off. I decided to pull the power and set back down. I pulled the power, let the plane sit back down and upon the nose gear touch down, the shimmy came back but much worse. I was actually wondering if it was the nose wheel or something significantly out of balance with the engine. I never really looked at the air speed indicator but I looked at the tach and noticed that I still had 2200 RPM and was having a difficult time getting the RPM's to come down. I have the vernier ( screw in and out ) type throttle so I began back screwing the throttle. Everything finally slowed down and I taxied off and back to my hanger. Upon inspection of the nose wheel it appears that the bolt that appears to hold the little coil spring posts centered, has bent. Or maybe it was bent before I started. I also want to point out that the free castering nose wheel self centers when you lift up on the front end, a test I was told indicates that you have the right tension and such on the nose wheel. In testing a couple of them at the gathering, I noticed they did not self center and those owners indicated they had no shimmy issues. By the way that information was not meant as any criticism of anyone else's KR. I just wanted to compare my nose gear adjustment to others while there. Here is my question. Did I let the nose gear touch down with to much speed thus precipitating the shimmy? Did I do a poor preflight and this centering bolt was already bent ( Slightly, spring still looks to still be contained ) ? Is it possible that I let the plane stay planted to long and had to mush speed before I pulled the nose wheel come up? Thus precipitated the whole thing. Maybe I need to look at the nose gear at the point of the engine mount / fire wall? Your thoughts experiences?
