Thumbs down

I am restoring a 1972 Lynx 292 for my nephews, and a little me, I couldn't find a .020 piston anywhere but my local used parts hookup had a NOS std cylinder for it. My question is this, when setting the timing the AC book I have specs out to .158" BTDC, another book I have says .218" BTDC, neither book specifies whether or not to set the timing with the advance in the retarded position or the advanced position. Any one out there got the proper procedure?

By the way the 05 f-7 is siiiiiiiiiiiiiiiiiick

My book says .0256" BTDC measured at retard. Your info must be in advanced position.
Point gap .012 - .016"

There is supposed to be a stationary mark on the block at base of cylinder and two holes in flywheel plate at outer rim. One hole, the left one should line up with piston at TDC and the right one at 10 deg. BTDC this is the one you should use with a timing light or buzzer.

Hope some of this helps.
