Got them water blasted, have had other stuff done and i love the process.
I keeped one carb complete and used that as a guide and re installing all the other parts and pulled that one apart as i went.
There was only 2 different length screws (only prob 3mm lenght difference) and everything else only really has 1 area it can go. Hardest part was the the spring area as there is a heap of parts in such a small area.
I didn't bother with the throttle shafts yet. Unsure if this will bite me but wont know till i try and get it running.
Price wise it has only cost me about $300 to do the rebuild.
