I thought I would reopen this thread due to prior interestregarding the solution Rossi had in solving the 10mm carburetor issue. I received three new idle needles from SG on Monday. I tested all three carbs on the 60LS with an APC 11x7, Omega 5% (10% and FAI blended, all I had), and the Jett Stream 60-90 muffler. All carbs functioned much better in the idle and mid range transition to high speed.

I plan toinstall the carbs on an engine currently on a plane and fine tune in the air.

I have enclosed a picture withboth the old and new idleneedles side by side for comparison. The new needle is2mm longer and appears to have less taper. This seems to be a good solution.
