Thanks HiOctane, I'll give it a shot!HiOctane said:Try first muriatic acid from the harware store.Use Q tip or something like that and spread it over the stuck aluminium part.USE IT IN A VENTILATED AREA,its nocive.After spreading it,wait lets 30-45 min,flush it with water and some aluminium should be gone or easy to remove.After few appilcations done and cleaning,hone it to finish.
thats true it may but you need to get that perfectly clean and smooth or you will just keep destroying pistons over and over again. take it from me i have been there.snoeproe said:no need to bore a cylinder unless it is gouged or grooved.
all that is is aluminum from the piston on the cylinder wall. a little muratic acid will clean most of it off. then a hone will finnish removing all the aluminum, it will be good as new.
