Help ID this carburetor. Never seen one like it before

[aeromech]

I know over the years that I've run into a fair share of cheap Chinese parts for air cooled VW's but this one must take the cake.

34PEAK-3

Google or samba search hasn't yielded any info. Just wondering if anyone here might have seen this before. I can't get it to not stumble off idle. It's mated with a 009 so I'm wondering if soldering up the throttle plate hole might help?

Hahahahahahaha!, another fine product from Sum Ting Wong industries, that's some funny shit!

You don't need a throttle plate hole with an 009 so close that up, also check the top cover for flatness, I've seen a few Chinese carbs with horribly warped covers that don't seal the vacuum and idle passages that pass through them. Also check the choke pull diaphragm, the Chinese just can't make a decent one it seems.

Thanks Mark. Yesterday I did the ultrasonic soak and rebuild thing but it still runs the same, like shit. I also did an honest Solex yesterday and it runs great on the same test engine. That one has the hole plugged. This is definitely a carb issue.

So who makes the best rebuild kits?

Thanks Tim. Kinda pricey.

$20? They cost that 30 years ago

Check the accelerator shaft linkages for slop and wear. This POS EMPI carb had a HORRIBLE off idle flat spot/hesitation. Basically, you're pushing the throttle and instead of IMMEDIATELY getting a spray out of the nozzle, you're only getting the movement of the slop before it finally starts to push the accelerator actuator. I have another German Solex 34-3 that was doing the same thing. It's linkage was wobbled out and sloppy as well for many years of use.

I don't know about that wang chung pow carb you have there but.. the Solex 34-3's have that accelerator adjustment (see the picture above) to increase the accelerator spray on the linkage. You may need to fatten it up and make it spray quicker/fatter.[/img]

Tried that and it did help but still not good enough.

Last year I bought three of these kits from Century Distributors in Visalia. They just have smoking prices. You can see that it cost me $6.95. I'll call them tomorrow. From what I see of the pics online of the $22 kits, they look the same as this one.

Check the accelerator shaft linkages for slop and wear.

This is probably the problem. I'll take a look. Right now I'm rebuilding 2 Bocar 34pict-3's and a Solex 30/31 with the 34 intake adapter. My goal is to run each on the test engine and dial them in.

Here's a video. This video shows the engine with a different carb (last week)

127.5 is usually adequate. A 132 makes it puke black smoke sometimes, and cuts HP by probably 5 - 7 HP.

34 PICKED 3.

The built 34 of them, and then picked 3 they thought might work.
