I am running a 1956 ( I think) 235 in my 1953 3100. I have a couple of oil bath air cleaners that don't fit on the carb. ID of air cleaner is about 2", OD of carb on engine is about 2 3/8" with a ridge or ring around the top. Is there a carb that I can put on the 235 that will accept the oil bath ? Is there an adaptor that I can put on the present carb to accept the oil bath? The little chrome paper filter I'm using now looks lousy. Thanks
