  1. Question cause I cant find a diy video I got a 3 1/2 hp briggs that will fire and run but when I turn the choke off to run position the wheels start spinning as if your giving it throttle!! any help would be appreciated!

  2. I just love Briggs and Stratton engines,they have a wicked sound!! I have always wanted to build a motorcycle with one but with 4 or 5 speeds, have you ever seen anyone do this? everyone seems to always have just one gear,centrifugal-clutch?    

  3. that sound is amazing dont mean to be a smart ass or anything but when you ride and tune put your airfilter on or else the air counter acts like a vacuum on your air intake adaptor
