Okay need some help here........ took carb b/c I was going to put on an FCR carb........ changed my mind...... so went to put stock carb back on the quad. Now i put the carb on and went to start it up and now when I rev it up it cracks and pops when you let off the gas........ I have curtis sparks full exhaust system.... 195 main jet stock clip position sparks filter with no lid......... ran fine up until now........ tried adjusting air/fuel screw mixture.... did nothing....... I have a feeling that it may be a vent tube to the carb but no really sure...... i put the air box lid back and it didn't back fire hardly at all on the deceleration.... does anyone have a pic of they're carb so I can look at vent tubes?? or if anyone has ideas......... thanks.
