the other day I was trying to disassemble the engin for maintanence, prep for media blasting and paint. while I was doing this a nut fell through one of the holes in the rocker arm cover and fell in to the engine. I think it must have fallen in to where the lower cam chain sprocket is or at least some where down there, because now as I am trying to take out the cam I just cann't fine enough slack in the chain to raise the cam enough to clear the sprocket. I followed the instructions on the manual the tentioner is not appling pressure and everythng seems fine but I just cann't figure it out. Now if it is the nut that is down there how do I fish it out the space is way too small I cannot even see down there. I was thinking of hanging the engine upside down and moving the chain, maybe then gravity and the movement will dislodge it, if it is really stuck I was wondering how hard is it to break the chain and where I can find a new one.
