Adjusting Ignition Timing "When checking engine timing with a strobe type timing light, disconnect the vacuum line from the carb to the distributor. Engine should be at idle speed. Connect timing light high voltage lead to wire going to Number 1 spark plug and the appropriate low voltage leads to the battery connections per timing light instructions. Be sure to check polarity of connections....stock electrical systems are 6 volt positive ground. Loosen distributor hold-down bolt and adjust timing by twisting distributor until timing marks line up between groove on pulley and indicator. Tighten distributor hold-down bolt and re-check timing. Re-connect vacuum line to distributor." The above from Vanpelt's site > http://www.vanpeltsales.com/FH_web/flathead_tuneup49-53_239-255.htm eBay is a good source for the test equipment you require....> https://www.ebay.com/sch/i.html?_from=R40&_trksid=m570.l1313&_nkw=6+volt+tachometer+and+dwell+meter&_sacat=0

Hi...Set the point gap with a feeler gauge, and use a twelve volt battery to power a timing light. Yes, there is vacuum at idle, so disconnect the vacuum line to the distributor. You may have to raise the carb idle a bit when you do this, and plug the open end of the vacuum line. BT

Does anybody have a source for a reliable 6V analog dwell and tachometer? Also, if the engine is idling, why would it be necessary to disconnect the vacuum advance to set the timing? Is there some advance even at idle? This is a in an 8BA. Thanks!
