I HAVE A QUESTION I HOPE SOME ON ECAN CLEAR UP FOR ME. IN COMPARING A 72 AND71 CARB I KNOW THE 72 WAS FOR ALL FUEL A'S IN 50 TO 52 AND THE 71 WAS FOR THE GAS VERSION IN THE SAME YEARS. WHAT I HAVEN'T BEEN ABLE TO FIND OUT IS WHAT THE DIFFERENCES ARE BETWEEN THEM . I PULL A 51 A AT THE PRESENT TIME WITH A 71 IT IS BORED .45 OVER AND HAS ALUM PISTIONS . I HAVE BEEN LED TO BELIEV THAT ALL FUEL WAS A HEAVIER DITILLANT THAN GASOLINE AND THAT THE FUEL ORFACE IN THE 72 ARE BIGGER THUS LETTING MORE FUEL THREW ORIGINALLY BECAUSE OF THE HEAVIER FUEL BUT NOW WITH GASOLINE IT GETS MORE GAS AND AIR TO THE ENGINE THUS HELPING PERFORMANCE ON A USE WITH GAS. I HAVE DYNOED A 51 AND KNOW IT LOSES WITH IT WILL THE 72 HIT THE HAPPY MEDIUM FOR ME OR IS IT THE SAME AS THE 71 AND WOULD I BE WASTING MY MONEY ANYONE NO THE ANWSER SURE WOULD APPRECIATE SOME FEEDBACK THANKS JD PULLER

Don't know about the specs on the 72. I have a 52A bored .045 with iron pistons. The fuel orfices on the 71 carb have been reamed out slightly to increase fuel flow. Most guys around here opt for the 51 carb used on the styled G's. I've heard some even install D jets. Don't know how difficult the latter is to accomplish but the G carbs definately seem to help.
