Sticky petcock

(1/2) > >>

kiro29:
It's not sticky anymore,
I've disasembled it, clean it with carb cleaner spray from STP lubed it with WD40, and the most important I believe it's the spring which is to strong and forces the conical teflon part against the top of the petcock, try to crush the spring with a plier to make it softer and check the diference.
It's beautiful now.

Good rides

If it sits unused that doesnt help,glad to hear you got it to work.

kawdude:
I've got the same problem and I have not taken mine apart...yet.  Is there a way to set how heavy the spring pushes on this?  What made the difference, cleaning it or smashing the spring.  What's the spring in there for???  Do you need it?

kiro29:
I dont know, this is a very small spring that's used to make some pressure inside to avoid any leak and to make the tap not to move around with vibration and the legs.
I crushed it all the way (2 - 3 mm), and cleaned it because it has a kind of aluminium dust in it, anyway what I think it made all the diference was to crush the spring, I didn't try to take the spring out but yes I think you need it.

Try it it works very well.

Sharc:
Cool idea. I have the same problem. Next time the tank is low I'll pull it apart.
