Anybody ever had AV disintegrate the needle o rings on their holley? I tore into the bowls and the orings were almost gone, unatomized fuel was bypassing the whole time. Just trying to figure out if it was the fuel or the extreme heat or both. Also I forgot to add a bit off mystery oil till the next day not sure if that had something to do with it as well.

First needle from primary bowl(oring completely gone had to clean the sludge of it out of the bowl)
Second needle from secondary bowl( oring expanded and ready to break)
Third needle ( 30 year old needle from an old holley 750) just for comparison
