First car. HR Holden. First tune. I pulled the distributor out of the block walked inside and called my Uncle who was a mechanic,..."how do I set the timing" was my question to him. He answered, "well you need to turn the dizzy to advance or retard the ignition",.............................(Me)- Well I've pulled the dizzy out so I could o it over the phone ,...................(Him) Did you mark the exact spot so you can put it back correctly?,...........(Me) yeh,nah. (Him),............Well you're about to discover how to work out where TOPDC of cylinder 1 so you can set you the firing order correctly.................We still have a chuckle over that one!
