    i have a grubee 48cc that when running fast will back fire then act like it's running out of gas until i back off the throttle. :confused:
    After reading nearly all the boost bottle thread i wonder if that might help with this issue. vibration is also an issue. And would like to remedy this :poop:
    Question 2: putting in a #7 plug... i'm riding "trigger" in 100-110 heat for 15 miles, is going from #6 plug to #7 heat range going to help ? Thx J
