Roxy: Free at Last!

Finally got around to freeing up the stuck float pins in both Roxy's first carb as well as the spare that came from the PO.

To brace the posts, I used a small piece of the scrap 22ga steel from the alternator cover project and cut two notches with the cutting wheel, taking only a little material off at a time so as not to overcut.





Then used a C-clamp to start the pin moving, one end braced on the steel and the other one pushing the end of the pin.  Once I got one end flush with the post, I used a wooden punch to knock it out further.  Finally pulled it free with some needle nosed pliers.  Started with the S90B carb.  For reference this carb has 85/35 jets in it at the moment.




Able to get to the 1.7 float pin for the very first time.



Then went on to the S90K1 carb (Roxy's first carb) and found the pin had notching that matched notches inside one of the posts.


Also discovered, and this was somewhat expected, that the needle jet is unmarked.  Not only that but even though it's "close" to 8mm, an 8mm socket does NOT fit it!  Luckily the socket fit just enough to get it loose. For reference, this carb has the 85/38 jets that came out of the CS90C carb that's in Roxy now.



The tool itself was remarkably simple but completely effective.
