The gt40 i picked up has some pretty heavy carbon build up inside. Aside from having a shop dip it( if possible ), what would be good ways to clean this thoroughly.

I cant complain, only cost me 175 for U&L.

 

sulfer bath or a heat wash with chemical

 

dipping it in gasoline and brushing with a toothbrush

 

wtf.....torture him.. toothbrush and scrubbing sucks (but works)...hops #9 bore cleaner removes carbon build up bathe it in the stuff, and bam a little hot soapy water to rinse it and it should clear that stuff up

 

paint stripper for an hour or two then wash it out does wonders but you have to worry about rust then. probly spray some anti rust gelly in there or soemthing

 

wouldnt spraying jelly inside it.... as silly as that sounds [8D].... reduce air flow? i imagine it wouldnt be too smooth of a surface.
