Once the idle tubes are removed, the passages for the idle restrictions and the idle tubes (they're next to each other in the main body casting) can be properly cleaned out.
If the idle tubes were removed carefully, they'll go back in using the original collars just fine. Otherwise, Ruggles sells replacements, both pressed (like stock) or threaded.
I tried once to remove them but they were pretty much stuck in there and I feared damagin 'em, what would be a good way of doing it? heating up the casting maybe? what would be a good tool to grab them without crushing?
thanks for the tip, I'm sure this will cure some of my "junked" q-jets
