I assume they are like any Holley?
I have a 750 DP.
Can I change the jets without removing the carb?
I assume you take the 4 bolts out holding the bowl on and you will get to the metering plate and jets?

Jim,
Same jets and gaskets as those of a Holley. Use the largest
flat blade screwdriver you can get into the jet slot. They
are super tight from the factory. Yes, take the bowls and
metering plates off as a Holley.
I have observed they are a little rich (which is good) on the
primary side out of the box. I usually jet them down about
two sizes to start with.

So it can be done still attached to the intake manifold?
I have not messed with one in years. I just do not want a lean condition and have a meltdown

Yep, just change them like you would a Holley. Remove
one screw and use a small container to catch most of
the fuel and then break her apart.
Gaskets and the stack up are the same as they are in a
Holley. But just like on a Holley, make sure to hold the
accelerator pump arm up so it will go back on the
throttle shaft cam when you slide it back together.

My jets were extremely tight!! They appeared to have loctite on the threads when I finally got them out. Like OLDRAT said, use the largest flat blade screwdriver you can make fit. I chipped one of the jets when I removed it. I purchased a jet tool for the next time I change them out. Good luck!
