2 clips? WTF. How do I know if I have a 108?
Pilots are at 2 1/2

There needs to be a washer above the clip and another clip in the first groove,  otherwise the white plastic retainer won't hold the needle down tightly. When  replacing the white plastic retainer, make sure the feet don't cover the  slide lift hole in the bottom of the slide. The main jet should be a 108 and the  pilot screws 2 1/2 turns out. Again, these are the baseline Dynojet installation  instructions.

The clip is on the 3rd from the top. hmm, is that    right?

Steve Northrop <blackgpz at>    wrote:                   That's the needle that dangles from the slide. You can see it's tapered      at the end. The slide raises and lowers the needle relative to a fixed      orifice depending on engine load. The main jet is below the needle and      provides the fuel that is below the fixed orifice. Whenever I have the carbs      off and the slides out, I take a little crocus cloth (very,very fine      sandpaper) and smooth out any rough spots, especially on the "wings". Inside      the slide is a white plastic retainer that just lifts out, then the needle      can come out. If the needle has little grooves at the top with an "e" clip      in one of them, a jet kit has been installed. If the needle just has a nail      head, it's stock.

Ah! Master Steve,
 The problem is that I don't know        WTF I have. Nor do I know
very much of what I'm doing.
1. But I sure        can compare the springs from my stocker to No.2.
When I pull the        diaphram up & out (thats the main Jet dangling
off the slide        -right?)

2. Shouldn't the slides be very smooth in        operation?

3. um, what else is down inside        there?

so,          compare the diaphragm springs to the stock ones. If they're shorter          
than stock they are NFG. These kits are notorious for an off-idle          bog 
if you use their springs. Replacing with the stock springs          solves the
