I have a 1962 Falcon Club Wagon/Econoline with a I6 170 and a Holley 1904 or maybe even a 1908 (I cannot tell the difference) with manual choke. The problem first started out with a leak on the float bowl. I had the carb rebuilt and it still leaks. The leaking problem appear to be that the float bowl is bowed/warped. I was wondering, is there another type of carb that is straight bolt on replacement that I can use?
