Reconditioning GS450

Good stuff!

With the mixture screw, were you turning it in or out when it got stuck? If it was turning in, it could have bottomed out and bound up, so be very careful when removing it as you don't want to break the tip off.

You definitely want to free the screw up so you can get your mixture right otherwise no amount of jet changes will be able to compensate fully for that.

It may also make synchronising the carbs a little more challenging.

Hey Pete, I was turning it out when it got stuck. It's about half way out and now I can't seem to rotate it in either direction. I'm afraid to force it any further as the threading is already pretty stripped. I'm going to borrow an impact screwdriver and try that, but the only other option I see is drilling it out and replacing the mixture screw.

Good luck on replacing the screw, they don't appear on any parts fiche's that I've seen so you can get a part number

I wonder if it's far enough out that it's just binding on the O ring?

Try a couple of small flat head jewellers screwdrivers and see if you can just pry it out gently.
