then its something custom or one-off.
have you seen AJ's adjust-a-jet holley carbs?
it may be something similar, just on a stock carb? |

That's funny, I just mentioned an adjustible main jet earlier today in another, and for that, took a picture of one I happen to have that fits the 34 series carb. It is a one-off, I think I've only ever seen one other like it before.

| The main use of an adjustable idle jet would be for altitude changes depending on the carb type. Now for drag race you would want to adjust the main jet also for corrected altitude as the day changes.. |
