Default Q-jet problem

My quad (its a 207)started dripping out of the boosters today when I fired it up. This is the first time it has ever done this. Checked the float with no luck. I can rebuild a holley in my sleep, but this is the first q-jet Ive ever run. Any ideas. Thanks guys.

A COUPLE OF QUICK THINGS TO CHECK , OBVIOUSLY YOU'VE CHECKED THE FLOAT LEVEL. 1) CHECK THE NEEDLE AND SEAT
ESPECIALLY IF YOUR RUNNING THE .130 UNIT AS THEY MATE VERY CLOSELY WITH EACH OTHER AND COULD EASILY NOT SEAT CORRECTLY. 2) FUEL PUMP PRESSURE AS RELATED TO #1.
3) CHECK THE PRIMARY BUTTERFLY'S THEY MAYBE OPEN TOO FAR AND PUTTING A HEAVY "SIGNAL" ON THE BOOSTER TELLING IT TO PULL OVER. IF THAT'S THE CASE YOU WILL HAVE TO PLAY THE "HOLE" IN THE BUTTERFLY GAME TO CLOSE IT BACK TO NORMAL. 4) CHECK TO MAKE SURE THAT THE FLOAT IS NOT TAKING ON FUEL.

HOPE ONE OR ALL OF THE ABOVE HELP......NORM

Ed, if you can, tell me what your float level is, what your needle and seat diameter is, what your fuel pressure is, what your idle RPM is, how many turns from having the butterflies fully closed it takes to get that idle speed, and if there are idle holes drilled in the butterflies. Also, what is your timing set on? It's REAL hard to fix one over the phone, nevermind the Internet, but I'll damned sure try.
