Can you snap a pic of the air filter side, inside? I'd like to see if it has that "lip". 

Yep - I'll pull it off tonight to change the jets and snap a shot!

Totally forgot to take the picture last night. I ordered a second one and it will be here tomorrow. Your picture is the first thing I’ll do when I open the box!

Where did you order the new one from?

Same guy on eBay - scooters_to_go. He is selling them for $30 now and it appears to be worth it.

What kind of bad luck have you guys had with Amazon? I ordered my front tire, fuel filter, and usually buy sliders through them. The only scooter bad luck I had was ordering front-end kit, the vendor was unresponsive so I just canceled and ordered somewhere else. I have otherwise ordered all sorts of other things from Amazon, including all sorts of car parts - clutch, flywheel, plugs, etc.

Amazon can be good, but it requires some know how on which parts to source, which brands to trust and which sellers are legit. Much of the really affordable scooter product on Amazon comes from Chinese companies that perform little to no QC, or verification of the legitimacy of their parts. This is how we (as an industry) end up with 20mm carbs that aren't 20mm, fake Gates, KOSO and OKO product all over the place and generally sub par products that proliferate throughout the ownership base.

Sure, a Glixal part seems OK... until you get your hands on the real deal and then you get an idea of what you pay for when you get a legit quality part.

After some 'searching' (had to use advanced to be able to find the store)

carb & 3 jets 35

carb alone 30

These look to be the same as the Glixal China sourced 'Keihin' carbs. They have the manufacturer label cast into the side of the body by the throttle control, and some have the name and 'technology from Japan' on the plastic cover.
Read the 'full description'(another page pops) on ebay,
vi.vipr.ebaydesc.com/ws/eBayISAPI.dll?ViewItemDescV4&item=182402769921&t=1495054981000&tid=10&category=82205&seller=scooters_to_go&excSoj=1&excTrk=1&lsite=100&ittenable=false&domain=ebay.com&descgauge=1&cspheader=1&oneClk=1&secureDesc=0

and you'll find some are reported as being labeled 'Keihin' on the black plastic, others not. The Glixal sold carbs I bought had the name in the casting and on the black cover. I ordered 2 from the alibaba store, for ~$22 each, delivered, and they sure looked to be exactly the same. For a couple bucks more, and some wait time, I have two available to install along with a couple BB's. The shipping is listed at about $9 ea, so you are at almost $40 per.

They look very similar but it performed MUCH better than the Glixal. I ordered 3 Glixal's from Amazon ($23.99 each shipped, same day) and have returned all 3. It is possible I just got a bad batch, but the one from scooters_to_go is noticeably better.

[GrumpyUnk]

I bought one of these, (could't resist at $17.50) and it is very similar to the 'Keihin' from China, and indicates it is from Japan... It appears to be of better quality than the 'metal' capped carburetors. I have not tried it yet, but if it works, I'll be pleased.

At the bottom of that page are several other listings. They do not claim the "K" brand, but some are actually labeled, as is the one above with a maker name. That in itself tells me something, they want people to know where to get another... I think. But, it could all be more fake out the customer.. Dunno, so far.

What did the Glixal carbs do? or rather NOT do?

I ordered a 20mm from scooters_to_go on eBay and I am blown away by the difference between it and the Glixal. Not only does it run perfectly, it improved my top speed about 6mph! It is branded Keihin but I don’t think Keihin makes a real 20mm based on research and feedback from the forum. It bogged down at about 41mph so I’m guessing I need a little bigger main jet (it came with a 80 pre-installed).

Can you snap a pic of the air filter side, inside? I'd like to see if it has that "lip". 

Got the new one - also branded Keihin and here is the air filter side.

I have one of these keihin clones also, funny enough its plastic cap has a different looking “K” symbol type thing

[dexameth]

Ahh my bad, I meant the intake side... haha

Here you go!

[dexameth]

Looks like a true one, if it measures 20mm in the bore. No "step" like some of them have... that should be a keeper.

I happened to be at the Taotao warehouse today (long story) and asked if they had an extra carb I could grab. They brought me one labeled PD19J but it isn’t sealed! I figured they must all arrive straight from China sealed but I guess not.

I believe they are sealed because of emissions when installed on a scoot that they're importing. A carburetor and other parts can be imported without the same scrutiny.
