I found this on a miafiori rebuild - same carb...
Write down the jet numbers from primary and secondary. Also if
you do take apart throttle shaft, use a piece of wire, and as
you remove stuff from the shaft, slide it on the wire in the
same order/orientation. That way it's easy to put it back.
If you do take everything off, you can take it to a specialized
shop to dip it into carb cleaner fuild and ultrasound tank..
That should pretty much get rid of everything..
The alternate method I used on my TLDE (take a look at the pics
before/after) is the following.. After removing EVERYTHING off
the carb, I took a deep dish, filled it with water, put the carb
in, and put in A LOT OF STRONG detergent. I used a non liquid
laundry detergent - a very powerful one.. Put it on a stove, and
let it slowly boil for like 30 mins.. Make sure that the temp
changes are gradual.. Get a pair of good rubber gloves (so you
don't get burned), and a good nylon brush, remove the carb parts
from the hot water, and clean them (TLDE has like 3 sections)..
Just don't put it under cold water.. Sudden temp change would
destroy it/crack it/deform it.. Also with the water still warm
take it outside, and for every little hole in the carb body
first dip it into hot water, and then blow the water out with
air-gun... It is far more effective to clean passages in the
carb body with the water pushed by high speed air, than just the
air itself.. Just make sure that you removed everything first -
you don't want parts flying around, or jets damaged by water..
Also you can repeat the detergent procedure a few times (I did
it twice).. After you are done, do the same thing, just without
the detergent this time.. That way you will get rid of any
detergent deposits inside the carb.. The carb looks virtually
new.. Just for the kicks, I took it to the carb shop for
ultrasound cleaning afterwards.. NOTHING came out.. The guy was
amazed by the carb body, and asked me how I did it - he claims
that ultrasound thing never gets it THAT clean.. Just be careful
not to hurt yourself (ie hot water flying out of the carb
body...). Assembly in reverse order
.. Get some carb shaft
grease, and use it.. Not too much.. Oh, and removing the
throttle plates is a bit tricky.. Well worse than a bit...
That's the hardest part.. Maybe you should just stick to the
basic rebuild
..
