Hi. Trying to find the following Holley jets. Help needed, thanks. The Primary Main jet is: 22R-130-215. The Secondary jet is: 22R-130-550.

Have you called the Carb shop in Ca?

Where did you get those numbers from, and what carb are you working on?

thinking those are #S for a 5200 holley / webber if so look up jets for the webbers version

Very old carb and numbers
Holley numbers direct from a Holley employee
450cfm economaster holley four barrel
List L-7456
Modal 4360

They are 1/4 - 32 pitch

Also will check into the Webber just in case

Not sure if I ever tore into one of those, but if the threads are 1/4-32 they are the same as any gas Holley jet. Can you measure the passage size? Picture?

Those old Economasters are a good carb! I had one on a 355 I built for my 73 Blazer. I pulled my Stude with it and it performed flawlessly! Lotsa throttle response and still had a good top end! It seems to me it had progressive secondary linkage but no rear squirters, nary a bog nor stutter...

Yes you are correct

As it is a old carb and thus I live in New Zealand the 215 and 550 main jets i cannot find on this side of the world.

I have emailed both the carb shop in ca and Daytona park but as yet no reply

So it's frustrating as I know what i need but cannot get it here and no contact back from the states but we keep on trying.
