my cc qjet is giving me bog when i punch it. it happens when the car if fully warmed up and going at any speed. i adjusted the AV spring a while ago and the bog was nonexistent until a week ago. shound i readjust the AV or is something else wrong??

 

Check first to see if the AV adjustment lock screw came loose, and if the adjustment is where you left it.

If all of that is okay, then the next choice is the choke pull-off. If it isn't holding, you'll bog.
