The float bowl of the 28G carburettor from one of my tractors was full of corrosion . The alloy it is made from is fairly soft and there is a difficulty in getting abrasives into the intricate internal workings .
I made this soda blaster from a few bits and pieces . A normal dust down air gun with a long tube nozzle is the basis . The nozzle is fitted into a piece of plastic tubing about 2'' from the end . A piece of conduit is fitted to the pick up end to add weight and keep the soft tubing straight .
To use just place the end into a box of ordinary kitchen grade Bicarbonate of soda . Once finished the soda dissolves in water or degreaser and no residue is left .
Finished bowl

Nozzle in tube
My small direct drive compressor worked reasonably well , higher pressure and more cfm would have to see better results .
