X flows timing is easly checked from start to finish,
Basics
The notch in the front pully is like a chisel mark not to worry there, No1 spark plug out long thin screw driver down bore bring piston to top dead centre, rocker cover off see if No 1 Rockers are top dead and No4 is rocking, that will inform you timing chain hasnt slipped.
Distributor cap off, Rotor at number one points open you should have enough twist left and right on the Distributor body to get the ignition timing, now i can't remember if the Distributor is on a worm gear or a peg, with the extention on to the cam a worm, maybe the worm gear is 1 x tooth out if the point arm is well before or aft the Distributor cam loab i would be looking to see if the Distributor is miss aligned.
