On eBay I bought a carb, the person said it came off a 1990 Trail Boss. After putting in new jets it works OK. The problem is, the carb has a a choke or primer that is operated by a lever mounted on the carb and the air screw is on the right side looking toward the engine. It is a Mikuni carb, but is not a stock Trail Boss carb. Does anyone know what machine this type carb was used on. I now have a carb with the correct choke on it and I want to resell this carb on eBay, but I won't lie about it, I need to know what it could have been on originally. It came off something that you could reach the carb to operate the choke.

 

I'd take a wild guess that it's off a motorcycle of some sort, rather than an ATV... try googling the part numbers if there are any stamped on it.

 

I thought it had to be on some type motorcycle, but I have never seen one on a machine and If anyone has ever seen a machine with a carb like this, please reply. It should be about 250 CC.
