Put muffler seal on any possible leak points...
I prefer to run a left and right bung... check both
sides and see if you have a lean and rich side and if
you do try a stagger jetting but if they are close
then dont worry about which side... just mount it so
its easy to get at... make sure its above 3 o'clock
and 9 o'clock so moisture can drain out... once you
get a reading on both sides you can chip off the muff
sealer if you want then get another set of readings
with the so called leaks and use that as the base line
with the difference from the sealed readings... I
dont like putting it in the X due to it seeing a pulse
and not straight flow(straight flow gives you a better
and faster reading)
gasses are on the higher side of the exhaust,from what i was told.It works good.
