1950 panhead spark control


Post by Parker » Mon May 16, 2011 8:29 pm

My spark control pulls and pushes the cable wire in and out (in for advance when hand grip turned counter clockwise and out for retard - clockwise) when not hooked up to the circuit control but when hooked up it will pull the wire in for advance but will not push it out to retard. Took the wire out of the cable cover and it moves fine. in and out freely. Have all the correct mounting brackets but no go. I took the grip off the throttle side and put on the spark side of the handle bar just to see if it worked and it made no difference. Any thoughts as to what to check. I have run out of ideas. Just seems that when under "load" it will not push the wire out!

If the outer cable is not connected to the spool within the handlebar you can have those symptoms. When pulling in the cable will butt against the spool, but when pushing out it will move with the inner cable within the bar.
Also, is your circuit breaker base greased?

my cable was doing exactly the same thing. My timer was tight. The outer cable housing was stretching inside the handlebar because the plastic coating on the outside of the cable had deteriorated. Was acting like a spring. I replaced the whole cable and all was well.
