The new plugs seem to have solved the rough running and this morning went for a short drive with 3 stops and it seems to run just fine. Questions linger, like why the plugs fouled in the first place? When I do a vacuum reading the vacuum appears to get better as I open the needle past 2 turns upwards to 2.5 turns it will bounce between 19-20 on the gauge. Is this OK or is this why it was running too rich? Was my issue of fouled plugs more caused by the plugs only being gapped at .035? Timing was at 15 btdc with distributor vacuum disconnected. Now it is set at 18 btdc as recommended by Faron Rhodes. I have the plugs at .045. Any suggestions? How often should I check my plugs?
