I flew mine a couple of times yesterday, all went well, no issues.  The accelerator pump carb makes starts so easy, the throttle response great.  I did open up the cowling area as compared to last year, and revised the throttle curve.  It was turning the Vess 18-6 about 9400 on the ground.  The other thing is, I flew with the SFG's on the EF Extra for the first time and it really makes KE's just stupid easy with alot less rudder.
