At least we now know that the # 3 retard was > real, for at least SOME distributors. It carried on up into the FI distributors. I have seen it myself.

Just the Bosch number. Example: ZV/JCU 4 R 3. That is a '64 1500S distributor. > > Russ, were there other pages that also showed advance curves for other type 3 > dists with retarded # 3 cams?

I am sorry, but that is the only one I can find right now. 15 years or so ago, I got rid of a bunch of stuff that I thought I would never have a use for again.

Funny thing is, that VW recommends the timing 2.5 degrees if you encounter pinging/detonation. About the same as what they retarded #3. -- Russ Wolfe '71 FB AT '66 FB MT '64 T34 (not running) '65 T1 (not running) russw@classicvw.org http://www.classicvw.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
