I've experienced this a few times already.. and it seems to happen when the OAT and/or oil temperature is below 50F...
Engine cranks normally, but when it catches, the engine will run very roughly for 1-5 seconds. I thought maybe one of the cylinders wasn't firing, but I see the all the EGTs rising while the roughness is happening.
Advancing the throttle seems to help clear it.. but without knowing whats causing it, I can't say if the throttle is actually helping.. or if it would have cleared itself up on its own. Another RV12iS owner reported similar behavior under 50F.
Here is a video (sorry the quality is crappy.. but I needed 3 hands to film it.). Hard to see, but the OAT is 47F; Oil Temp is 52F. Wh-ile its being rough, it looks like the gets up to 840rpm and all EGTs are between 180-200F. Oil PSI gets up to 4. Throttle position was initially set to 54%

Any ideas?
