Tried almost everything and still can't get the timing and gap right on my '76 308. The distributors have single points (R1) and owner and shop manuals only describe gap and dwell settings for dual points (R1 & R2). Also, the flywheel is marked 3', PM 1-4, 7', and 37' in that order. Not the same as in my manual (TDC, 6', 16', 34') Don't know what the gap should be, don't know what the dwell should be and don't know which timing mark on the flywheel to use. Have already set the gap at .30mm, set the timing at 7' and the car drives retarded (depress gas and it chortles and acts like it wants to stall). Interesting, everything seems ok with gap at .30mm and timing set at 37' but afraid that is too advanced and might damage the engine. Have constructed a bench test for the distributor which I can mount it on a wood block which then is mounted on my drill press and can spin the distributor while at the same time adjusting the points. Now what I really need is a step-by-step procedure for setting the gap, dwell and timing for a 308 that has single points with a 3', PM 1-4, 7' and 37' flywheel. (BTW don't know the purpose of the 3' marking?) Thoroughly perplexed. Have set the dwell to 34', 39', 68' and 78' (on the bench tester) without success. And the dwell measured when the distributor is installed in the car never matches what is measured on the bench. More perplexion.
