My engine now idles fine and starts fine after considerably amount to trial and error and setting time. I checked the vacuum pressure close the vacuum diaphram and it showed healthy ~20+ in when I gave throttle. But no throttle I saw the distributor got sucked to do some vacuum advance. Will that happen only on load like engage transmission or distributor should get advanced by vacuum as I start giving throttle. The reason I ask this is I get some pops thro carb and there is some afterfires in exhaust. Just wanted to confirm before I buy a new vacuum diaphram.
Thanks in advance
