Dellorto jets

PERHAPS THE IDLE JET WAS BORED TO THE LARGER SIZE OF 60 ??? THAT'S A COMMON THING.............................................

Never heard of an odd number like that?

The carbs derived from Italy and if you were to open up a carb that was pulled directly from a say a Fiat or ? you will notice the jetting corresponds to a smaller motor and the jets will be noticeably smaller. The carbs sold here in the U.S. are all sold with the larger jets and a 45-55 idle jet is the norm.............

Am I missing something here?? Idle jets come in many sizes for Dells. I just went bought 3 different sets in the fifty range. Many guys don't realize the are not just for idle. If you want more mid range power up the idle jets and in some cases you can them decrease the size of your mains for better gas mileage, yet the same top end. Joe
