Hey DaRock, what is this thing that is extended out of the wood? That thing that i thing come from the carb. It looks like a piece of linkage i think. It's on the right of the photo you post.
That's the needle valve extension. It's a braded wire with a collar at the end. The braided wire can be cut to almost any length. It does not transmit as much vibration as a solid wire would transmit. And the collar can be placed to match the length.
The needle valve body has a gib screw setup in it. You can place a solid wire extension or the supplied braided wire one. Nice feature.
BTW, guys used to make their own braided wire extensions all the time in years past. Any braided cable works and small collars are easy to find.
