ok I have a serious problem. I put the flywheel lock pin in the hole of the flywheel and then put the blocks on the back of the cylinder over the 2 cams locking them in place so everything would line up to tdc. lined up the cam sprockets and chain also. once it was all lined up I removed flywheel pin and cam blocks and tried to turn the crank around a couple of times. It went a short ways and locked up like it was hitting something. I removed the cam sprockets and chain and moved the individual cams - no problem there. I then moved the crank and same thing happened. It felt like it was hitting a valve. I moved the cam a bit and the crank turned freely. at tdc the pistons should not be hitting a valve. Anyone have an idea whats going on? please write back, am at a loss. |
