Dyno tuned this season for Q16 and made power gains on 14:1 SBF N/A over C-12 used last season. Container says to drain carb after each use? Ok, what about the pump, regulator, lines, etc. Is this really necessary? I was thinking of draining and then running some 93 pump gas thru at idle to purge the Q16 but then where am I at when I go to the next race? My race schedule is about every third weekend.
