Quick update. I flushed the carb out multiple times with carb cleaner and never got the motor
to idle. In the end I left the carb in cleaner for a week. Turns out this isn't the brightest idea as the plastic (there were pieces I couldn't remove) melted to some extent and coated the whole piece.
So I said **** it, and bought a new carb. The motor
now purrs again and is able to lift
the two of us onto a plane in our new 310 compact RIB
, but only just.
I've still got the old carb, and one day when I have some time might make another pass at cleaning
