    Where can I buy a set of standards to check dellorto  PHBG 18 BS carburetor main jet orifice.

    I have main jets from 80 to 100 and suspect some of being the wrong size for their markings.  I need precision set of standards to check the orifices.  Can anyone help?

    We flow tested for consistancy and found that all the Dellorto jets are slightly different. Some are way off. If you suspect you have jets of the same # that aren’t the same your probably right.

    Brian Degulis if it’s not asking to much would you explain how you flowed your jets please.

    Hi Chad,

    You can use a set of pin gauges to check all of your jets.  Here is an eBay auction for those:
