Trying to find the connection that sits on top of the MC2100 carb to allow a remote air filter @ tube set up. I saw on here a few years back a unit that looked like a small round air cleaner that had a 4" tube outlet so you could connect a remote air intake to it, can't find it again, I looked on Summit no luck there either. I'm hoping someone on here has a MC2100 with remote filter, thanks for the help and any advise or pictures. The MC2100 has a top 5-1/8" to mount to.
