Even more sloppy on the big blocks because in addition is the play in the right-angle worm drive gear to the distributor body, whereas the small blocks have it direct on the end of the camshaft? If I’m torking rowlocks don’t be afraid to say so Even when I tried it with my gear-driven camshaft blimey it still wanders about a bit
Guilty of being a plonker One of the recent fettling ‘tasks’ was find out where the timing is wrong and put it right … Just operating on the basis for the sake of argument that for where the rotor ridge and pole-piece are lined up = ‘zero’, then mine was about 3 flywheel teeth (11 - 12°) retarded! What the hell was I thinking … No wonder it seemed ‘mild’ …
I’ve been tweaking it but just had a proper look at again this morning, to make absolutely sure ~ tank off, dizzy cover off, alt. cover off, bung out of bell housing; line up to RH TDC by allen key in the alt. bolt; OK make it so rotor ridges and pole piece are lined up (almost was already). It’s got to go advanced soon as it starts turning. Has to be better than what it was! Starts and runs alright anyway. One consequence was had to back off the throttle stop screws like LOTS AND LOTS.
