lol - I would quote my freinds saying "thora munasib karlo bhai"
anyway carb rebuilding - first get a spec sheet for the carb you are rebuilding, then open up everything and mark and label them on a giant piece of paper,
clean out all passageways in the carb body and if the throttle plate is worn - fix that first - now start to reassemble - piece by piece - with the spec sheet infront of you. to seal the throttlebody to the carb body I would use permatex 2 (its petrol resistant and seals up metal joints nicely)
For cleaning - heavily corroded carbs would require a sweeping but usually carb cleaner - an assortment of brass brushes - not steel for Gods sakes. will clean it like new. By Clean I mean surgically clean and every little airway should be shiny.
I have a solex carb repair manual at home in Karachi - it tells you what circuit to tinker to achieve what and the overlapping etc. And do remember to check the heat riser for blockages - if it is blocked - your engine will stall after a few minutes with a perfect adjusted carb.
