China 660 clone. Anyone else have a tank leak?

[Stevetheboatguy]

The tank on my clone weeps/leaks on the rear seam. It's not a horrible leak, but there nonetheless.

Any ideas to seal it up without uglying it up?

I have heard about a few early ones that did. Not sure if they were repaired or replaced.

I imagine that would make the saw fail a pressure test. If it is new, I would ask for a replacement.

If not, I'm not sure if Loctite 529 would work on that or not, but that is what I would try.

The caps always seem to leak, but are easily fixed with a 55 cent O ring gasket from an auto parts store.

How does a fuel tank factor into a pressure/vac test?

I dont believe any sealant would "look" good. For the price id just get another tank. But if is a new purchased tank id be asking the seller for a replacement. You shouldn't have any trouble getting a defective tank replaced since you are not citing a problem with how it looks you have a problem with it working as it should. I mean i doubt the seller had to modify or mess with your money you paid before spending it so the same should apply to your parts purchased.

Seems can sometimes be repaired with a soldering iron by melting the crack shut. Sometimes additional filler is needed. Trimmer line works, but on a stihl with the white tank it will look ugly unless you can find some nuetral color.

I guess my thinking cap was not on tight!

It's a new saw. I ordered it from hl on one of their after Christmas sales.

The reason I'm trying to fix the leak is. Tanks are on backorder. They don't have a replacement to send me right now.

So I figured if I could get this one sealed up without making it ugly. I wouldn't worry about getting a replacement.

It's not a huge rush on getting it done, but I do have some larger wood that I would like to see how it preformed compared to a oem saw. And I'd rather not get fuel leaked on me or have it split all together. Know what I mean?

SOP here , I pressure test every tank on my rebuilds and vac test the breather.

I think I am going to start doing that as well. Would only take a few minutes.

I often test the carbs in addition to the saw.

Lots of gas flip caps leak.

 

[MustangMike]

Yes, but not always on the first time. The O rings from the auto store work a lot better than those flat washers that stretch way too much when you tighten them.

Always on used ones.

The new China ones sometimes have the lever set wrong, and it leaks (results in a saw with hydro lock, very hard to start).

All fixed up. The epoxy job wasn't going to be a good solution. Maybe for a quick in a bind fix but not a permanent one. @Gentleman was able to get me a replacement tank and all is good now.

Fuel is coming right through the middle of the cap on mine. Maybe they thought it should be vented?

 

[MustangMike]

I've seen some of them do that, even OEM. Don't know why they seam it like that!
