Following my incident last Saturday I flew 3 times yesterday without any issues with the engine.  The outside air temperature was similar on both occasions. It may be useful to have a straight connector handy to replace the primer bulb in order to prove/eliminate Simon's theory should the problem reoccur.  

Crsfrwll, did Parajet mention which model of Walbro WB carb they plan to use?

This seems to be a theme. I experienced this issue yesterday at about 50 ft after take off, releasing the throttle to about 1/2 and reapplying and it cleared. I had to do that 3 times. The rest of the 20 minute flight (close to the field) was fine. My Atom 80 has less than 5 hours on it and I'm using fresh fuel with Motul 800 oil as recommended. Nothing obviously amiss with the kit. Worrying.
