H/W Jet #s Question

[Williboy]

So I hooked up my AEM O2 sensor this afternoon and dove headfirst in jetting 101. As soon as I started the car the AFR went to 10, I then adj with the idle mix screw and nothing happened. So then I went to check out the Idle jets and noticed one was missing!!!! I take a quick look around and notice it laying in my motor mount. Well the threads on the holder are shot so I need a new holder. But I yanked out all my jets and came up with some interesting numbering on a couple.

Mains: 315 & 223
Air: 195 & 165
Idle: 70 & 60
Emulsion Tube: 05 & 16
Pump Jet: 4

From reading the Sticky Post on H/W Jetting I can assume that the Mains 315 = 150 and the 223 = 130.
But what is the 05 & 16 Emulsion Tube #??? And the 4 on the Pump Jet, would that = 040???

Also, on the Sec side of the carb the idle jet screws all the way in while on the Prim side the screw (holder) stick out a bit. I found this info while looking around that mentions that some Weber DGV's had two size of Idle Jets. Has anyone seen this on a H/W 5200?? I bought it new from Stovebolt many years ago.

I'm planning on stopping by a local Weber shop for some better jets in range what I read in the sticky

Sorry for the long post. I DID read the sticky and it answered alot of my questions

When you say the threads on the idle jet holder are shot I gather that those are the threads on the outer surface of the jet holder. Are the threads in the carb OK? I think all the idle jets for DGVs and DFVs are the same OD and length. Is your jet seated completely in the holder. Did you clean the holder and the idle jet hole. If the jet had fallen out you may have sucked some crap into the hole and now the jet can't seat completel.

Yes the holder threads are damaged not the jet. It got smashed by the motor mount. It was the Sec that fell out. The Primary jet is the one not seating 100% Here's a pic of the different jets for the DGV .

The one looks shorter but that could be the pic

I tried it w/o the jet and the holder screws in completely. As long as the jet is in tight would it still work?? The side hole still allows flow.

I'll try calling Stovebolt tomorrow and see what he says and I'll stop by the Weber shop.

I checked my #4 pump jet and it spec out to .040, so I think that is right. Any ideas on the Emulsion tubes?? The Weber site says the baseline #'s are F50 & F50. Some else posted 94 & 93. Those don't show up on the Weber charts I can find

Not sure about the idle jets, but I'd think that as long as they seat they'd be fine. May want to put a helicoil in there though, if they come that small.

On the emulsion tubes, from what I gather you'd have to have a chassis dyno and a lot of time to be mess with them. They basically determine when or how fast the air corrector bleeds come into play, iirc. I wouldn't even think about them until you get the rest of the jetting set, if then even. My emulsion tubes aren't on any id charts either, fwiw.

I called Tom @ Stovebolt but there on vacation till 4/7 and I didn't stop by the Weber shop yet either.

From what I read and understand emulsion tubes basically mix the air and fuel which is regulated by the main and air corrector jets. Adjusting with them are getting into detailed tuning. I'm just wondering if mine are close

Here is an long forums discussion on Weber DG V carbs on an Opel forum, I found. They mostly run 4 cyl, so they jet smaller but there is alot of good info

I'm going out of town this weekend so I'll have to get back to this next week. I'll post if I get any good info
