I JUST CHANGED THE JETTING ON MY CARB, AND IT WAS OVERALL FOR THE BETTER. BUT I NOW HAVE A DECELERATION POP.

I WENT FROM A 168 TO A 164 MAIN JET(HAD TO PUT AIR BOX LID BACK ON TO RIDE IN PA COAL MINE..A LOT OF DUST). AND I ALSO SET AIR SCREW FROM 2 TURNS OUT TO 2 1/2 TURNS OUT.

I LOST JD JETTING INSTRUCTIONS AND WAS WONDERING IF TURNING SCREW OUT LEANED MIX, OR RICHENED(WHICH IS WHAT I WANTED). IT ONLY LETS OUT ONE POP(EXHAUST), NOT SEVERAL .

ALSO THE POP DOES NOT OCCUR EVERY TIME MAYBE ONE IN TEN TIMES.

DAMN AM I NITPICKING OR WHAT
