SBM Distributor overhaul DIY?
I had done a quicky mapping a few months ago but nothing detailed. I just know that it's all in by 3000. Pic shows how it was setup. Maybe heavy and medium?
The vacuum can has an 11 degree arm and the limiter has 17 stamped in it. So that would be 22 crank degrees with vacuum and 34 mechanical? I had been running no vacuum, 15 initial and it seemed like it topped out at 36 at 3000 but that doesn't make sense if the mechanical limit was 34 unless it wouldn't open all the way.
I'm doing this because the timing bounces a bit at idle and doesn't seem stable . Car doesn't idle well in gear until it is good and hot and will still stall now and then. Going to see if more initial will help.
Can you elaborate a little bit? I can see areas that looked like they had grease, but what type/weight? Light oil on everything else that slides? Don't want to gum it up so I'd lean towards lighter grease and motor oil but oil tends to sling off and that felt doesnt hold a hell of a lot. There was a pile of crud in the bottom of the housing. Is that the collection area?
It's all cleaned in the ultrasonic tank now and ready to go back together.
