I have my idle set at 850 rpms so I am barely off idle at 1000 rpms . But I may try moving the baseline to 18*. I just dont want to screw up the idle transfer slot position or have it idling at 1000 rpm . I will be hooking my vacuum advance to a ported source ( only source) so that will kick my initial timing up 6 or 7 degrees as well as any low speed crawling I may be doing .
At least thats my theory....
