hey guys, thought i would start a new post as i seem to be jacking everyone elses threads lately....
i have never done this before, so there will be questions
so here it goes, some before pics, after a slight polish and repair on the float bowl screw threads, had to re-drill and tap m5...
its always good to make a reference and mark each carb, i scratched the corresponding number in each foat section:
you need to remove some parts, not all pictured below, i only thought of this now...
but here are some:
this puppy here needs to be removed to the left if looking from the same direction as two oics up. be sure to loosen the throttle cable assembly thing with the spring and the two ends that attach it to the base plate, also pictured next. There will be two keys that come expose themselves after the shaft starts moving out (to the left) so keep them safe for reassembly later on.
there are also linkages that you need to remove with little ball joints on the ends that operate the slides.
there will be two of these, i will be replacing these o-rings from a industrial o-ring supplier and the fuel resistant type. i will, be posting sizes of all the o-rings i will be replacing so you all can save a few bucks on your carb rebuils..
i then removed the butterflies:
next i removed the choke butterfly shafts, make sure you note the order of all the washers and stuff, so it makes your life easier later on when you assemble.
i then whooped the tops off and removed the small nut holding the shaft in and removed the slide with the needle.
I found a sort of grease in there? or was it old sticky dirt? 
also, see the floats, they get removed after the float bowls are removed, a little punch can be used to push the shaft out. mine were all stiff, they should be loose-ish. on the left is the shaft that holds to slide assembly in. be sure to remove the felt washer from the shaft bush area, it keeps dirt out (it might go missing when the cleaning process starts) place all washer etc back on the shaft after removal so you know here the bits go later on.
i then removed the float bowls, the main jet retaining spring, the main jet (o-ring will be replaced), idle jet, needle and seat (o-ring will be replaced too. The emulsion tube was a pain to get out, it comes out the in the same direction as the main jet. do not damage the top when pressing on it to remove it, as the needle needs to slide in and out of it. mine was very stuck! but after a bit of brain storming, they all came out:
here is the needle and seat (o-ring will be replaced), with the main jet and idle jet which gets removed from the outside, it screw out and there is a spring under it. normally you would screw each one in until it stops while counting the turns, so you know where to set it when re-installing. Unfortunately, mine were all out, so i never bothred
in for rich and out for leaner mixture. (I have done a lot of reading huh
)
fully stripped:
then after some cleaning with thinners, i soda blasted them with this DIY piece of kit:
http://www.aircooledtech.com/tools-on-the-cheap/soda_blaster/they did not come out all shiny, but that didnt matter! they are clean and beautiful!
with some decent advice from harisuluv: no need to rinse them off after blasting (i was concerned with corrosion as the thinner left a white residue after cleaning them in it)none the less, they were super dirt free and dry before i blasted, so there was no reason why the soda would/could stick in any part of the carb. thats good
so after all the blasting, i cleaned all the orifices out with compressed air for a while i might add, not because there was soda coming out, but because i wanted to make a million % sure they were all clear
you will notice with the air shooting in all the the orifices and where they end up and make sure they are all clear. if they were dry to start off with, you wont have any issues
in the next few days i will be getting the all the o-rings needed for a complete rebuild including the float bowl sealing o-rings. will post sizes too as mentioned above.
some parts will be replated (dont like paint where there is fuel) and replace the main spring.
the jets and brass bits will be cleaned and serviced, so they can be reused.
thanks for reading
