Does anyone know what the stock jet size is for the carb on a 84' GS (both for the primary and secondary)

Sterling

You can replace them with Holley 10-32 Air Bleed jets.
Napa will want 27 bucks for a ten pack, which is half what Mazdatrix wants, but they are all the same size. So get the smallest you would use ( .036 ) and drill some out. You just need to buy a variety pack of drill sizes from .036-.065 and a pin vice to hold the bit. Drill by hand, not machine.
(Unless you're doing alchohol jet drilling, it's not so crucial to obtain orifice perfection. But do try to drill as clean as possible. Use a drop of oil.)

Stock primary is .036, stock secondary is .063 . Don't go much higher in the secondary. Even our modded carbs including the SterlingCarb don't get shipped with jets higher than .060.
Going higher in jet sizes by more than .003 may require a pump upgrade and a regulator.

In metric the stock sizes are 92 (primary) and 160 (secondary). This is for a manual trans car.

Thank you Sterling and Rx7carl. I searched for probably an hour tying to find these numbers and never could find them.

I was just interested to know what they were. Thanks again
