heat riser stuck open, leave? remove? or fix?

I'd leave it. If you free it up, it's eventually starts to rattle...ask me how I know.


Leave it as is, if it is truly froze it is not going anywhere.
I hear you on rebuilding them they are a pain, and never seem to work 100% even after rebuilding.

Rebuild kits are expensive...
