jet adjustment on jawa supreme

I've been struggling with getting fuel flow through the carb on my Jawa Supreme. I found some manuals online which refer to the the "jet adjustment." How does one adjust jets? The manual says the main jet should be at 63 and the idling jet at 35.

Anyone have any experience with this?

You don't "adjust" the jets, you have to remove and replace them to change the air/fuel mixture. However, I think that the Jikov carbs have an adjustment screw for the idle jet (but not for the main jet).

If you're having trouble getting fuel through the carburetor, check the float and float needle while you have it off.
