This worked for my sons Tao Tao 125 atv. Although my bowl was pinned instead of screwed so we had to drill those out and tap for screws. After that, the adjustment you suggested of the tab holding the needle worked and she is running great now. Thanks

Finally someone who knows how to explain how a carburetor work! I just got my quad and every video I’ve seen has too much detail on the thins I don’t want to know! Thank you for the video! A tip to putting back throttle needle. It’s easier if you hold the gas while you are threading it back on that way the spring doesn’t fight back.

Thank you for the help ,I just got a pagsta 2004 w/649 miles only,it sat in a garage untouched for 11 yrs,nothen wrong with her ,she just will not stay running or ideal, put new battery, and plug,and gas line and filter,so I'm going to rebuild my carb,and ones again thank for the help ,great video.

[@05molinatsx]

Thank you!!! you just saved me a ton of time ,and some money, i was able to get it just rite!!! I was warming up my sons new surprise birthday present and found that it was dumping out fuel and you saved the day!

[@tk_gunteralan]

Yo this video was amazing thank you so much dude! Got my 110cc super pocket rocket running again with no leaks after this! You da man

[@jeromefitzsimmons2228]

Thanks, I just got one of these PZ20 Carb's and it poured fuel out air filter and thru bottom overflow after minor use ... I returned it and ordered a new one (before I saw your video)... I suspect the new one may need an adjustment and now I'll be ready. Also, you're very right about easily striping screws putting carb back together... take it slow and switch sides screwing to balance the screw torch

[@jhman9800]

Exactly amazing video, wished I stumbled upon it earlier, I used the same tube blowing technique really helps in giving you an idea of when the needle closes, I have a 125cc pit bike that tends to surge when I give it quick gas so I pointed it out to too lean a float setting so I did exactly what u did, crossing my fingers in hoping it runs right after. Again great vid

[@deansmith9341]

Great Video, question, should the Carby breather screw be tight under normal operation?

[@ryansolomon5083]

Using your breath to act as gas is what gave the some here that "ahhh-hah" moment lol

[@bees1357]

[@mrsuarez430]

Unrelated but i have a new mercury 4 stroker 2.5 hp and it had the carb replaced with a new one and it leaks crazy amounts through both vents it runs funny thing is i took it in for service again and didnt do it This is exactly what i thinks going on the float isnt set correctly from manufacturer.Got stranded yesterday lol anyways good vid bud

[@jamesward5721]

This looks to be a Keihin knock-off. You'll find 1001 people complaining about Keihin carbs leaking fuel both out the overflow & into the engine itself via the airbox breather pipe - you'll also find 1001 "solutions" of varying faffery - the gist is press the plastic float unit up as if the bowl is full of fuel. If the plastic float touches the metal of the carb when in the "fully up" position, it ain't seating the cut-off pin onto the port - you need the plastic float to stop before it "bottoms out" in its travel - you do that by tweaking the small metal tab that carries the shut-off - you want that shut off pressed home on the port before the plastic float bottoms out. Open a few & you will find the float almost always bottoms out before the shut-off is pressed fully home - so that carb will always leak fuel, no matter what other measures you take, how much cleaning/blowing/cursing you do. The first step is to make sure the shut-off is being set firm onto the port before the float runs out of travvel. Simple as. If it isn't - adjust the tab. You want that float bouncing off the port, not the body of the carb. Then - hey presto - it'll shut the fuel off as intended.

You're dead on. Any carb you get needs to be opened up and inspected, especially a knock off, since those who build them get paid by how many the produce in a hour.

[@chrisclemons9943]

I got one for my kids. It leaks gas from the bottom with the motor off. And it won’t start. Any ideas what could be the problem.

[@waynewootton5385]

i have a 1991 polaris sportsman 500 4x4 it just started t leak gas into air filkter box ....Help.

[@dangerousdoggo5465]

Hello, is this the same carburetor as the PZ16? I'd also like to ask if the part where the intake manifold goes is 16mm.

[@EngineerPrepper]

PZ16 and PZ20 are pretty much identical.. the difference is the intake diameter. Pz16 is 16mm and pz20 is 20mm.

[@dangerousdoggo5465]

@@EngineerPrepper Oh god. I need the 16mm version, and the seller had PZ16/PZ20 in the title, and I ordered that. I texted him I want the 16mm one. I hope he sees it! How would you rate this carb? I need it for a 2 stroke moped. No reeds yet but most likely I'll order a reed kit.

[@gainsum]

7:20 I thought you had a fuel leak vent tube? So only when you go full throttle you dump fuel?

[@gainsum]

You said you need more fuel in the bowl... buttt doesn't that continue to dump excess fuel in the bowl?

[@zorandrobnjak5641]

Hey, since you mentioned vent tube, where should I connect that and what to do with screw that controls flow out of it? So far I only used it to drain excess fuel out when it overflowed.

[@godfellas483]

If you are going to make a how to video please have strong communication skills and learn the nomenclature of the parts you are working on.

[@dannygerhardt6057]

Stillll holding honestly there needs to be slow, average , understanding is what you do visual is enough . I can read….

[@lindsay-ei7xz]

don`t think your a carb guy, it`s a needle and seat your adjusting, where do you get off telling people how to fix things when you absolutely no nothing about a carb ???

[@bentallman7597]

Dude you have no clue of what your doing where’s your level at lol that’s all u really need is a float level and the factory settings on ur specific carb

[@abelcp22]

Thank you
