sorry, your post led me to believe you didn't know, as you said "so I know where to get parts for it when I need them."
again, mix & match hardly ever works...please read around this place before trying to debate basics with experienced folks...we usually discuss 2 different aspects of a purchase: "engines" and "kits." parts for "kit"s are much easier to mix than "engine" parts, but you still have to know what you're doing. i know your "engine" performs passably, maybe even better than, but i also know it's NOT an 80cc...and, IMO the "kit" is sub-par, especially for the price.
dax sells parts to repair or upgrade his kits & engines...some sellers do this...noone (reputable) we know of will openly claim to be able to supply you with parts for an engine bought elsewhere...mix & match at your own risk. as i mentioned, it can be accomplished if you do your homework ie: read this forum as much as you can.
please don't post a bunch of new topics about basics, that only makes someone else do the work for you...post a "reply" to an existing issue instead to participate in the organization of the enourmous amount of data we're scrambling to keep usable.
