Stihl 441 question

[Daniel VanMeveren]

Was wondering what I should do here saw was rebuilt with big bore kit shows 150psi cold throttle open runs good starts great should I run it it till it blows up or should I tear it apart and fix it right

I can’t imagine a 441’s aftermarket big bore kit making a good runner. That said, if it runs well now I’d run it until the top end fails and then fix it with OEM parts, barring the bottom end being worthless at that point. Then it’s junk. It’s a Stihl that had an eleven or twelves year production run, you’ll be able to get OEM parts for a while.

That kind of glazing rarely heals itself.
It will probably start, but will have trouble maintaining an idle without dieing, the worse it gets.
