yeah I figured down by the head but was looking and figured I could only get to one side of it. So just shooting it straight down towards the glow plug is the ticket right? I just want to make sure cause my starter box that came with my hyper 7 dont fit 100% correctly even after I did some tweaking on it, so I figure start with piston at the bottom, maybe a few drops of ARO and a heat gun to make it easier on everything.
