Timing Mark Indicator

[Hoop]

Charlie,

As embarrassing as it may be, your math is wrong. .755 is not the answer. And 22 1/2 degrees is not really relevant.

Additionally, if you read "Bored & Stroked's" post #4, he correctly uses a degree wheel to mark the pulley. You can make a cheap "degree wheel" by drawing a circle on a piece of paper the same diameter as the pulley and marking it off using a protractor.

(Cheap plastic protractors, those half-moon things we used in grade school, can be bought at any office supply store.)

These marks can easily be transferred to the pulley.

I'm surprised nobody mentioned the -6/+6 degree stuff. We are talking about crankshaft degrees in marking the pulley. -12/+12 ... this can be very misleading. Add up the max initial advance and the max centrifugal advance to find what marks you really should have on the pulley.

Again, just trying to keep Charlie out of the Jameson's.
