I got my FCR 39 from C & D the other day,, and I was wondering what jetting you all are running,, I dont know what size jets are in mine though... It idles great,, and the main jet must be good too cause it pulls hard from mid to the top,, but when you just straight up punch the throttle,, is bogs and dies,,, but when you ease into it,, then puch it,, it runs great... I need a couple of opinions if you all dont mind... Thanks..

I have a 170 main and a 50 pilot jet with the clip on the third notch down on the needle. It runs great. I adjusted the air/fuel mixture screw to get rid of the slight hesitation mine had when I first got it. No problems now.
