I ran the test again only this time with all plugs removed , full throttle, engine cold, and I gave at least 5 puffs for each cylinder. The results were much better. 1=165psi, 3=160 psi, 5=160psi, 7=160psi, 2=170psi, 4=165psi, 6=170 psi and 8=160psi.
The first test was done by pulling one plug at a time, no throttle, and one or two puff's.
