You do know how to change the cam timing by adjusting the sprockets, don`t you?1979 european engine with the cams that were installed when I got it. Head is off a spica car but I've got Dellortos. Chain is tight. If I move the intake cam it will be off as bad in the other direction. I guess it's worth a shot. I'll check the rotor too.
Very good instructions ANDREW!Five: once the sprockets can rotate separately from the cams, keeping the crankshaft at TDC, rotate the cams til the marks the line up. The sprockets and the chain and crankshaft should not move.
Six: tighten up the cam chain a bit, after having tightened down the 22mm nuts just snug.
Seven: find the vernier holes that line up and insert the 8mm head bolt and nut hand-tight.
Eight: tighten down the 22mm nuts more snugly.
