What does a carter YF carb look like as I took a carb off the 51 3/4 ton we had on the michigan property that definately is not a W-1 or a Rochester,all I know is it must of came off a 235 as dad had to do some grinding on the mounting holes to make it fit the 216 in the 51 and it seemed to be a beter carb then the Rochester thats on the 57 I have in my 37 and want to find a kit for it.
