Removed the distributors on my '76 308 to replace the O-rings. While I had them out I checked the point gap and discovered they were set at .004 to .003. The manual says .012. So I reset the gap and now the dwell measures only 10' rather than 39' as described in the manual. My 308, originally a U.S. version with dual points, was converted years ago to the Euro setup. Euro cams, single Euro points and Euro mufflfer. (The change made it a very fast car) How do you set the dwell? The shop manual describes a test bench setup but I don't have that. The points were last changed by the local Ferrari shop and since both distributors were the same when I took them out (very small point gap: .003), I suspect they know something above and beyond the manual. Puzzled?
