    Hi guys, I went on a long forest ride with my blaster, near the end of the journey it started bogging when the throttle was wide open. Once I got home I cleaned the carb and the air filter. But still when I accelerate its not smooth like before also it idles only after I cranked up the revvs in the idle screw on the tors even then hardly.Could it be air leaks? But how can it be so sudden, I also changed the spark plug for a new one but the problem persists, it's a stock blaster with all original parts. Waiting for suggestions. Thanks

    air leaks will produce hanging revs, it'll rev and not return to normal idle

    check ....
    air screw around 1-1/2 turns out ?
    fuel cap vent, run it with lid loose to check vent
    float height
    reeds
    plug boot for corrosion or burnt, unscrew cap, cut 1/2" off wire, re-screw cap back on, replace with NGK plug boot from auto store if bad.
    black ground wire at coil to clean bare frame
    woodruff key on flywheel not sheared allowing flywheel to rotate out of timing

    I checked everything, the reeds are brand new the carb și clean af, the only thing I haven't checked is the woodruff key on flywheel, could the stator be dirty and cause ignition problems?

    The carb is sqeeky clean, I'm suspecting the ignition coil or something ignition related I'm going to check everyting with a meter asap.

    Just measured everything, and the ignition coil is way out of spec. Gonna order a new one and see if it works
