low co2 during combustion test
Hello all. First post !! Did a tune up on a friends Thermo Dynamics series 110. Replaced the nozzle with same .85 80B. Pump pressure is 140. I have an -02 draft over fire and -04 at the breach. I get a 9 to 10 co2 reading at the breach using a bacarach wet kit tester. I cant seem to get the reading any higher. I have the air almost completely shut. I'm I missing something? Thanks...
