Re: [alfa] Adjusting timing on an 86 Spider, Distributor Position

[Gil Gagne <gilgagne@xxxxxxxxxxxxx>]

Kevin,

I pulled out my shop manual, just to be sure, and you are right: the 
center line of the rotor should be lined up with that thin line cut in 
the top edge of the distributor body when the "F" mark on the crank 
pulley lines up with the reference pointer.  The business end of the 
distributor rotor is rounded to provide constant clearance with the cap 
electrodes. After securely clamping the distributor base, check the 
ignition timing at 950+/-50 RPM and look for "F" mark on the pulley to 
line up with the reference pointer; this will be 11 +/- 1 degree BTDC.
