You say at the end of your post that it runs “GREAT!”.
If your only issue is “the needle is turned nearly all the
way in” what is “nearly”? 1/4 turn out? 3/4 of a turn out?
You say “The carb has been cleaned”? Just sprayed down
with some cleaner and wiped off or disassembled, soaked
in an ultrasonic tank or in carb cleaner and a rebuilt kit
installed? Cleaning and rebuilding of a dirty carburetor
will often require a change it the mixture screw setting.
Tubs.
A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
