YOSHI OWNWRS NEED JETTING HELP

I HAVE A HRC KIT WITH STOCK FILTER. AND OF CORSE YOSHI PIPE. I STARTED OFF BY PUTTING IN 185 WITH HRC AIR BOX LID ON. RAN OKAY. SO I READ ON HEAR SOME WHERE THAT TO TRY 195 WITH NO AIR BOX LID AND 2.5 TURNS OUT AND IT RAN CRAPPY. SO I PLAYED WITH SCREW AND AT 1.5-*2.0 TURNS IT RIPS AFTER ABOUT 1/4 THORTLE. BUT BEFORE THAT IT JUST FALLS ON ITS FACE AND WONT EVEN GET THE FRONT WHEELS OF THE GROUND. WOULD CHANGEING THE PILOT JET HELP? AND WHAT IS A SLOW JET? I AM JUST USED TO CHANGING MAIN JET AND EVERY THING BEING OKAY. THIS CARB IS HARD TO PLAY WITH
