Dual quads versus big hammer!!!...

How can it be lean if the air valve isn't open????? Jpar says the air valves are not opening. Can't be lean without air.

Tomorrow we will know more.
Wouldn't it need "air flow", or vacuum to pull the gas into the secondaries? And if he had that, wouldn't the back flaps be open? If the Demons are like the TQ's, then the back flaps are part of the syphoning process to get the gas into the secondaries. Fact that the rear flaps won't open under WOT is a concern
