Ordered one of these from Luke because I was burning the regular ones up so quick. Today I went to clean it and removed the alen screw that holds the bushing in figuring to clean it. The bushing didn't want to come out even after tapping it with a punch hammer lightly. I'm sure I could of got it out if I wanted to but figured there was no need to. Just drilled from the primer end to get the carbon out, put yellow teflon on and reinstalled. How are you guys cleaning these thing? Do you remove the bushing to drill through? I'm just wondering if I'm going to hut the bushing with a drill bit if I don't remove and drill through. This was the first time I cleaned the bushing and just want to know the proper way to clean. I'm using the .30 bushing. thanks

I never remove bushing. I take a drill the size of flash channel and turn it bye hand to remove carbon from flash channel. Then use a torch tip cleaner to clear flash hole in bushing. Then compressed air to blow it out . Air in can like computer duster works well at range. No worries about hurting bushing it is carbide so you wont damage it with any drill bit.

I drop plugs in a small jar with GM upper engine cleaner in it, its an amazing carbon cleaner. Its only vailable in spray can now, I still have the pourable stuff, but spraying some in a small container and soaking for an hour or so will get most of powder residue out. I don't know about the hardened primer residue 209 ignitions place in flame channel, but its great for Blackhorn as well. Ray

I use a 5/32 drill bit in my drill and run it thru until it hits the carbide bushing (as mentioned, you cannot hurt that bushing with a HHS bit). I then take a bit slightly smaller than the "C" drill and turn it by hand into the primer pocket until it hits metal. DO NOT do anything to the side walls of the primer pocket. You want that primer to be a force fit when it goes in (being cam'ed in by the bolt). I also remove the set screw in front of the bushing, run a wire brush on it and re anti-seize it. Forget about taking out the bushing---------------NOT necessary unless you want to replace it. Then you might need a little heat on the plug to get it out. A shot of compressed air from the bushing end will blow out all the powdered carbon from drilling. If you can see dust shoot out, you know the hole in the bushing is clear and you should be able to look thru it. Richard

If you have lukes rear sealing plug be cautious with the c-drill not to damp shoulder which is sealing surface for primer face.

Thanks for all the replies gentlemen. So is the trick to get the bushing out heating it up and driving it out with a punch when it's worn? Figured I'd ask so I know what to do when it's time.

Yes a little heat and proper size punch if have access to a arbor press is great for pushing bushing out. Even a bench vise will work. I like to push bushing out instead of driving them out. But it will be over thousand shots before you will need to change bushing .

I would bet Lucas fuel injector cleaner would take that carbon off fast.When you put it on your throttle bodies the carbon melts off.
