RE: ENGINE experts, help!!
BRUCE, again, as usual, I can't take any credit, the GHETTO GUNK BLASTER was one of those model magazine "idea page" contributions that I saw years ago. I've had one or two of these parts rattle out on me, and all I did was push it back in and cuss at it to stay put[>:]!
BTW, years ago I was taught by the local 1/2A GURUS to take all NIB COX engines, dismantle them and then sonic clean them over night. Amazing how much glittery, sparkly dust you find in the bottom of the jar.
