Default HSN Holder keeps on going loose

Hi

My HSN holder when I was running it last and this was after about half an hour became loose, I tried tightening it but it kept on coming loose.
I do know that the HSN should not be fully tightened and only by one or two turns once you feel the tension,
So what should I do to fix this, is it a good idea to use thread locker or green slime, I'm not sure at this point?

Thanks naz

If its coming loose then tighten it more. You should not need to loctite the needle.

You need to replace the two washers.
Once you get two new washers, it will stop coming loose.

Nothing else is going to help that.

It has metal washers already... Do you really think changing the washers will correct it?

Yes, that's why Novarossi recommends replacing them when you adjust the position of the nipple.

These washers are made of a softer metal, so they get "squished" when you tighten the needle holder assembly.
After you've done that a few times there's not much plyability in them anymore.

I figure what's happened with yours is it's been adjusted a few times and now the washers are wonky. So I think if you get new washers you'll be fine.

Right got ya, your right one of the washers has gone wonky, sounds like a good idea to change washers first and see if it fixes the problem.

I take it stronger washers won't hurt it?

Use the ones that are meant for your engine.
They probably only cost 2.50 anyway.
They are supposed to be soft, so that it won't come loose and will seal properly. Don't replace them with any old steel washer, that won't work.
