Salute All<br />I have a Year: 1971<br />HP: 60<br />WOT RPMS: 5000<br />Hydro electric<br />My question is about the link for the spark advance which connects to the top of throttle arm and then to the spark advance linkage under fly wheel. ive tried ordering it from several places no one has it anymore so ive decided to make it from alluminum rod but can anyone tell me the length of the rod to the bends? and is this rod really needed?<br />Thanks All
