ok -so my 170 six has a loadomatic distributor .
had the timing light on checking ignition timing - set it to 14 deg at idle(vac disconnected).
thought i would check it at full advance (cionencted vac line)- gave the ngine a blip - it went to approx 28 deg.
hmm not as muchas i thought . then had a thought ;
without a load (as its in neutral) when i blip the throttle - shoul i see full adavance ?
ie does a no load engine see enough airflow thru the carb to give the correct vac reading ?
if it doesnt see enough airflow - how do you check for full adavance ?
or am i seeing full advance and need to do something ?
