Does this still happen when the motor is warmed up? Sounds like it could be running a bit too rich at idle, or maybe the accelerator pump needs adjusting.

 

its is al the time, but I checked my ignition timing with a stroboscoop and it's now a little better, when i run ,par. ex; 2000rpm and I let my foot off the peddal the engine stays 1/2 second longer at 2000 and then fall ,,to idle 600rpm
