Hi I am a new to this mini bike stuff. ive posted on here already and got great advice but I failed to properly introduce myself. I recently acquired a Baja mini from a dude that baught it at tracter supply so im assuming its the mb200. anyway the thing was in pieces (a lot of pieces). but using this site I was able to get "humpty dumpty back together". I noticed that on the carb there was something missing (pic 1) then I found this bugger in the ziplock that was full of bolts (pic 2). what exactly is that for?:shrug: thanks
