Yesterday I went flying and tested out my new smoke system... everything was perfect... somke is fun. Today I head out to go formation flying.. nothing changed from my flight yesterday except for adding fuel. But it won't start... I verify that I have fuel pressure, fuel flow, injector function (in test mode), I have spark (in test mode). Maybe it is flooded... I change the plugs, re-verify spark in cranking mode (to eliminate issues with CAS), re-drain the fuel, verify compression, re-verify fuel pressure and flow and injector funcion... but still it just turns over without starting... Sigh
Anyone one know of a new component necessary other than fuel, spark, and compression?

Details?
Spins with no sign of firing at all?
Spits & pops but no regular combustion events?
Any chance that the extra effort required to spin the engine by hand using the prop through the reduction drive is hiding the fact that you have low compression? The old RX-7 starting trick is fairly quick if you've already got the cowl off. Pull a plug for each rotor & squirt in a little ATF, reinsert the plug & try to crank. Lyn can probably recommend how much. I never measured; I just dumped in as much as I could get in there while fighting all the junk under the hood.
