I'm building mine right now, I had to pull the fuel line out a little in the tank. My clunk was hiting the back of the tank and not moving freely.
I put the front susspention arms and carriers together last night, both sides bind slighty at the carriers. The first one I put one screw in all the way and then the other. I though that was causing the bind, not haveing the carrier lined up perfectly with the othere side. On the second one I started both screws and tightened them down evenly and it is still not free. I backed the screws off slightly and It didn't free up.
Any body have any ideas on freeing these up, or is it normal. On all the 1/10 scale stuff I have ever built I always try to get the susspention arms to flop freely and drop under their own weight before puting the shocks on.
