Moped Army

ok well i had to do some grinding on the inside of my 2 speed puch motor last night, i taped off the crank and then put some hot glue on top of the tape to make a pretty good seal. after i was done griding i blew the case out as best as i could(i dont ahve a air compressor) and then i noticed that there were still a few specs of aluminum shavings in my case. my uncle sugessted that we fill the crank area up with deisil fuel, shake it around a few times and then pour it into a bucked with a paper towel on top and see what comes out, we flushed it 4 times, and all 4 times aluminum pieces came out, the last time only a few small pieces came out.

i plan on flushing it 2 more times, but is using deisil fuel a good idea? he said use this over gas cuz deisil is less refined and contains some oil in it.

thanks in advance...
