While I was at work my mechanic friend has been busy.
He decided to purchase new o-rings for the pilot screws, just in case they were wrong/bad somehow. While out doing this he dug out the ultrasonic machine and dropped a carb in it. Turns out after multiple cleanings with carb spray and or pine-sol more stuff comes out of a couple passages, not a tremendous amount, but any is probably bad. So the pair is going to be bathed in the ultrasonic machine for some time.
The needles are N161 just as they are supposed to be.
This or little bike runs rich at idle and all speeds. The plugs showed this as well as the nose and eyes. No need to even get out the gas analyzer. The plugs are now the correct ones. Might not be today/tonight that the carbs are reassembled and installed. Will have more information after that occurs.
I might just sit around with a
and wait while the ultrasonic machine buzzes it's little self happily away.
