PeWe, any chance you remember or still have that advancer from the 75' Honda Cb750F? I am curious what the od was on its pin.
I see this now
That advancer has moved into my blue K6 with Dyna-S ignition.
-I do not know which pin you ask about.
I cut the springs as both my other TEC 300 advancers.
Stable idle, ign spot on F. Full adv at 2600-2700rpm.
I set ignition to match F at around 1000-1200 rpm.
Advancer has a several degrees lash noticed when nut is not tightened. Case mark will match with TDC (T) when advancer is in its counterclockwise position.
That engine has an alternative case mark 3mm to the right I use when timing the cam and advancer in its clockwise position. It will easy move to that when rotating crank with the big nut. No plugs in.
When done back to counterclockwise and set ign F to match stock case mark.
Bike had 104whp in October with good torque curve from low so ignition is fine. Shell V-Power street fuel.
