All the Chaparral sleds with their own branded engine used a Keihin carb, not Mikuni.

Although they have MIC on the body, I do not recognize the configuration nor can i find it in any of my books.
Looks to be a REPLACEMENT for the original carbs and should be 30mm size.

Look on the body and see if you find "B" or "BN" on it.
After another look, I suspect that you may have a "BN" carb.

found 2 ebay listings that look exactly like mine aside from the mikuni stamp
both say 38mm and one says off of a 340

Chaparral Xenoah Fuji Vintage Snowmobile Mikuni Carb Left Side 38mm | eBay

Mikuni 38mm Carburetors Chaparral Xenoah | eBay

so i believe it to be a bno butterfly carb

They look like Mikuni butterfly pumpers to me. RUN, don't walk, away!
Nobody likes Mikuni butterfly pumpers. Convert to Mikuni slide carbs, best way to go.
Same size should work, plug one of the outputs and use a dual port pump. That'll simplify your system and make it much easier to work on and reliable.

Yeah it looks like the two carbs you have each have separate pulse lines. You could always run two different pumps but thats extra work/cost/complexity I wouldn't want when a dual port pump will work just as well.
Just unscrew one port and screw in a short bolt of the same diameter. Actually in the short term while you're troubleshooting and getting everything working the easiest way would be to put a bolt into a piece of fuel line and stick that on one of the ports. I don't like that for long term, the fuel line will eventually degrade and you'll have a nifty little leak.

no problem. Had a chaparral early on. Which one do you have? This is a pretty good forum to get questions answered.
