What are you trying to adjust? If your idle stays high because of your pedal/throttle not returning all the way, you will need to add another spring in addition to the wimpy one that comes on it.
If this is what you're talking about, let me know and I'll post a photo of what was done to mine.
Outside of that, great carb...

Post a picture of your set up so we can see what manifold and such you are using to help you better.

Spring was installed to pull the throttle/pedal back into closed position, as the original wimpy spring would only partially close, resulting in high idle. The spring (yellow/brass colored, above spark plug wires) was installed by drilling a small hole into the carb support, even height with the lower end of the throttle mechanism, and then hooking the spring into the new hole and onto the lower end of the throttle mechanism. Solved the high idle issue. All other parts that I installed with the carb came with it in the box...
Littleray, you still have not clarified what you're looking for...

Does that carb have two A/F screws like a Weber DGAS?, If it does I would try closing one off and adjust it on the other but only on a open plenum manifold.

to catahoula lou, That's a great picture thanks. I'm getting a little pause when I step on the pedal. Mine has 4 adjusting screws, maybe I shouldn't have tried to adj some of them? |

To Catahoula Lou, My distributor is like the one in the picture except it's electronic ignition. I'm going to post a picture! I was thinking of going with an 009 dist? There's an adj screw behind the choke and I think that's the one I shouldn't have messed with. |

To earthquake, yes it does have 2 A/F screws, one in the back and one in the front. |

The reason why I ask about your distributor is that I had been putting up with a hesitation similar to yours with my 009. My neighbor gave me a box of VW stuff, including the SVDA shown in the picture and the hesitation disappeared when I installed it to test for selling on the Samba.
However, my mechanic says that he prefers 009s and can tune the hesitation out. Problem is, he had already done that, it came back before the SDVA installation, and I don't want to keep coming back...
If you decide to go with an SVDA, you'll need to use two vacuum hose sizes, slip one into the other, and secure as shown in the photo.

It looks like you do have a SVDA. Have you taken off your air cleaner and operated your throttle to confirm that both accelerator tubes are squirting correctly? If one or both are not squirting cleanly/strongly, that could be the cause of your hesitation. As I recall, you'll need to take the top of the 38 off and use a can of carb cleaner with a little red tube to blow all passageways BOTH directions.
On another note, find the instructions that came with the 38 and go through them again. If you don't have them, I can email a PDF of them to you, if you PM your email to me.
Also, can't see if you've connected the tube that goes from the oil filler to the air filter. If you don't have it installed, make sure you plug the air filter inlet, as dirty air will bypass your air filter and go directly into your carb/engine.
Ultimately, you might have to take it to a trusted mechanic once for a correct setup...

Also - run your distributor vacuum hose from the driver side end casting (like stock) and not the carb. That is an egr port and may not have enough vacuum to crank your advance when you need it. Then follow the Mixture Screw(s)/speed screw procedure in the instructions or on empis web site...similar to the progressive carb...it is basically the same as a weber dgas - which is the DGV carb family.. |

Littleray:
I bought mine from the same company, so likely same instructions. Can still send PDF if you want what likely will be a duplicate of what you already have.

Will email PDF of instructions. Also, found PDF of how I solved my hesitation problem at one point, by raising the idle a bit.
