This is a very rare Winfield Model N carburetor that has been in storage for many years. This carburetor is unusual in that it can be used as a down draft, side draft or up draft carburetor by simply removing the four nuts and rotating the bowl. I just finished restoring it and it appears to have had very little use in it's life and all parts appeared to be original to this carburetor and show little to no wear. Great carburetor to use with a Fronty head. The bore at the intake is 1 3/4". I don't think you will find another one of these. $1100 plus shipping.
Larry, just sent you a PM. Mike
