When I made my camshaft degree, I pot my other distributor in, the gear was better. Both are points type. One from a -68 4bbl. and the other from a -71 2bbl. After this I am having problems getting the all in on the distributor. It comes in early enough but too little. Everything in the mechanical advance seems to be ok, it moves easy and all the way towards the mechanical advance stop. Last time I checked I had to have about 20* initial to get about 32* total advance. I believe its the -68 I got in there right now, not really sure do. The question is: How do I make this (or any) distributor perform better? I need more mechanical advance! I assume I must alter eider the advance bushing, or the slot where it moves, But as Im not 100% sure how much mec.advance I got in either off them, any attempt to alter it without guidance, with my usual luck I most likely will end up in some kind off distributor disaster! My which is to have 16-18* initial and 34-36* total, these are the numbers I read all over this forum, and were able to get closer to with the other distr. Im also concerned that I might get some cranking problems next summer due to all that initial timing. Lars
The Short version. On a points distributor: How much (ore little) movement in the slot who restrict the mechanical advance is worth how many degrees mec.adv? Lars
Smartin's numbers are for the vacuum advance. On average, .005 (.11mm) is good for each crankshaft degree of mechanical advance.
