Is it worth trying to fix a cheap chinese carburetor?

I agree with Froth Goth's comments above. The cheap carbys are very cheap and you might as well buy a few for spares before that one also craps itself. If you are lucky enough that it actually can swap parts with the original, even better.

But what I really wanted to know from this thread is is it worth fixing a Naish Park? The octopus system is rubbish. I have two where the system started leaking badly a few years ago and now the valves have all fallen apart. As in the bits are actually decomposing.

Can someone find out what Naish use for these valves because they could have stumbled across a great way to make plastics biodegradable.

Which brings up the bigger question, when do you know its time to retire a kite instead of fixing it?

So, just to recap;

1) msn states he has a cheap chinese garden tool thingy that won't run.
2) he queries if a new carby is the answer
3) everyone tells him no, won't work, can't work, probably ain't even the problem, much better to try something else
4) he queries if buying a new cheap chinese carby is worth trying given they are cheaper than any of the suggested other fixing methods
5) everyone tells him no, won't work, can't work, probably ain't even the problem
6) he ignores the advice and buys one anyway
7) this fixes the issue

... Everyone now tells him the cheap ones are rubbish and he should swap all the parts from the cheap new one that works with the parts from the cheap old one that doesn't work, because this will somehow make it better-er...

....mmmmm, sometimes I think the internet is a tough place to get valuable advice....

I vote msn as seabreeze.com.au's new resident carburetor expert, taking over the mantle from remery, whose knowledge passed down from his father's father (which always seemed to include using a lot of vasaline) now appears to be redundant.

Which just goes to show that some people have very poor comprehension skills. Either that or I got a very different understanding of everyones replies. Oh well, I guess it at least tells me that hiding posts is a useful feature. Crack-and-talk should use it to filter out me too..

They all seem to have some incredibly complex gasket between the bits and I wonder if you can even get replacement ones. My guess is that you can if it has been copied exactly from the OEM part, but otherwise not. But then it becomes a question of whether you replace a $5 gasket to chase a problem in a $10 carby when it may or may not fix the problem.

Head gasket and two replacement primer bulbs included in package.

I thought these things are disposable as they are priced at under $200, So when last two broke I bought new ones. Didn't expect all parts are freely available. The same four-in-ones are sold under different brand names. Aldi sells one. The engines are the same from what I understand.

A head gasket or the mounting 'intake' gasket? A head gasket sits between the cyclinder head and the rest of the engine.

I replaced the carbies on a few 2-stroke engines I had. They seemed to work straight away but then the engines ultimately gave me the ****s and I went all the way to knock-off Chonda 4-strokes. They too seem to have their quality issues but are at least quieter and so far more reliable.

All right, all right, calm down, calm down.

remery can self-identify as seabreeze.com.au vice-president of carburetor advice if they want to.


I'm just voting msn as new resident expert no. 1.

At $8.67 for a complete unit why are complete units still questioning the availability of gaskets ?

The bigger question is does Temu take bitcoins ?

I am happy to admit I was wrong

I assumed it would need lots of farrr king around with the mixture screws to run but if it works straight up - valuable info

Mark - I can't comment on MSNs carb, but my mower carb doesn't have mixture or even idle screws. Set out of the box for the purpose, I guess?

But for how long will it work? Many of those small engine carbs have diaphragms to ensure continuous fuel supply when they are upside-down. The cheap rubber gets hard and fuel doesn't move around.

In my case, it was the carb for my old Briggs & Stratton mower. Very, very clear differences in quality between the original and the cheap replacement - even based on the pics when I bought it, so I didn't expect much. And wasn't let down. Cheap one failed in around 12 months vs 15+ years for the original. Been going great since I mixed the parts to make a 'good-ish' one. Mower itself is 20 years old, with some nice rust here and there due to poor maintenance, so wasn't really worth the $150 for a new OEM carb.
Cheap can be fine, as long as your expectations are appropriate.

If/when MSNs carb fails, he can replace the carb 20 times before it's more than buying a whole new unit.

The cheap primer bulbs like to harden and crack too....

That's why Temu give you two.

I'm currently restoring a 1970's mower with a Kirby/Tecumseh engine. The rubber primer bulb is perished but NOS ones are still available. The fuel tank is full of rust and presumably the carby as well

Nice! Is the mower restoration simply for a project, or is it going to become a workhorse?

This thread is of interest to me. I got hold of a 1950's Seagull outboard engine a few days ago. It hadn't been run for over 40 years. I cleaned it and the Amal carby up and got it running reasonably well in a wheelie bin. I put an advert on Facebook Marketplace and someone bought it withing 20 minutes. I have serious doubts a Temu carby would still work after 40 years. But maybe best check with Carantoc.

What were the fuel lines etc like on the Seagull? I assume still in good nick?
How did you clean the carb?

Back when I was regularly 'playing' with cars, whenever I'd rebuild a carb, I'd take it to work and drop the parts in a sonicator, after a good degrease.
Which reminds me, my Dominator carb needs a rebuild re: gaskets and clean.

I'm thinking the Seagull tank was made of something other than steel because there was no rust. But perhaps that's because it used to be filled with 10:1 two stroke, so maybe there was a coating of oil. I carefully dismantled the carb to preserve the seals and sprayed with modern-day carby cleaner. The fuel tap was leaking but seemed to come good overnight, maybe the o-rings expanded.My vintage Ducati has a Dellorto SSI 29 remote bowl carburettor, its finicky with the idle mixture screw impacting well into the off-idle range. But, once adjusted, its so simplistic, a spray of carby cleaner every decade or so keeps it in shape.

But best you first check with Croutontoc.

I know remery likes outsource his thinking, but alas, Carantoc has no idea of the serious or otherwise of remery's own doubts about Temu carbys. The only person who can elaborate on remery's own emotions is remery.

I'm no expert but.. I doubt a Temu carby will be still work after 40 years. But I also doubt that the cheap $200 pole pruner will work either. If msn had started this thread with "I have a classic outboard renown for their durability and longevity that has lasted 40 years and is likely to last 40 more, but has trouble idling smoothly, should I try a $8.67 carby from Temu as a permanent replacement"... then we might be a different point in the conversation here.

But he didn't. So we aren't.

Then again if your outboard has been broken for 40 years, you got it spluttering for 2 minutes using plenty of aerosol support straight into the carby, and then quickly flogged it on to some unsuspecting sucker, maybe a $8.67 carby would have been just fine for the Facebook marketplace scam.

I'm OK with being the primary go-to small engine (under 50cc) carburetor expert on Seabreeze.

Remery can remain the general expert on everything else.

Anyone here remember something in the media about a psychopath assigning different roles to people in his cabinet?

Is it always based on merit or something else? Are the people assigned expected to know what they are talking about?

P.S. Why do I feel angry after coming back from a 7 week kiting holiday? Is there something you can take to lessen the symptoms?

I think I have the answer, a 4 week kiting holiday, just to wean me off it.

Here's what's interesting about your comment.
Doctors and pretty much all medics are notoriously bad with money. Most governmental leadership roles are largely about the delegation of funds. So why on earth would we elect doctors to these positions?

Here's what's funny about your comment: where did FN mention Drs?

But in response to your query
Are you saying that the majority of our elected officials are better qualified to delegate funds?

Drs who end up in senior positions in organisations tend to have quite a few years experience as administrators.
Sure, your GP working in a chain practice probably isn't a good candidate to head up the national health department.
But a Dr who has spent the past 20 years of their career leading teams or heading up departments? That would probably count as relevant experience right?
