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
Thank you for getting back to me on this I was thinking of doing this but wasn't for sure what way to go thank u again for your adviceI 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.
