Good day to everyone,
I have a quick question concerning installing the small round aluminum buckshot plugs on the carbs. Basically is there any trick to ensuring a good solid tight fit. I know you can use a socket, wooden dowel, etc with a hammer but mine don't seem to tighten up and I make sure that the dome is flattened out for me and is flat. Basically I will be rebuilding my carbs by removing all the jets, high and idle speed, and all the small round aluminum core plugs to make sure I get all the passageways cleared out. So what is the most effective sure way to install these small core plugs so there not in there lose or possibly blowing back out especailly the very small one on the out side of the carb itself? Thanks Bob:)

I coat the edge of the plug with Aviation Permatex, gasoline proof. Lay it in the hole and use a punch slightly smaller than the and plug tap it in with a small ball pein hammer. All you have to do is flatten it by about 1/3 of its thickness and it will expand and seal into the carb. Usually there are extra sizes in the kit and you can lay one on the bench to practice how hard to hit it. NO 2&1/2 pound hammers!

Randy Beal,
Were do you get the Aviaton Permatex from? So let me recapp, first you put a small amount of Aviation Permatex on the edge of the buckshot, then use a very small hammer using a smaller diameter punch to flatten it out and that should be good? Now, you don't have to worry about the Aviation Permatex getting into your carbs jets, pickup tube?:)

I can get it at the local NAPA store. Just coat the outside of the plug, don't take much.

I just rebuilt mine. I put the carb in a vice and used a small 1/4 drive socket and small hammer. After it is in I used the old indian head gasket cement. It makes a air tight seal on the outside. I used nothing on the plug before I installed it. Had my boat out today and it went mint.
Good luck

Briannd386,
I never heard of Indian Head Cement. Where did you purchase that at? Can you get that at Napa, O'Reilly's Auto Parts, Autozone, or Advance Auto Parts? I am just making sure I do the carbs right this next time because I have cleaned my carbs out but never removed the jets or had any luck getting the round aluminum plugs back in and never ever used any kind of sealant on the aluminum plug after installation. I just worry that the gas will cause it to come off in time and get sucked into a jet and then have issues. I just want to do the job right the first time. If the sealant works fine then I will use it as long as it is gas/fuel proof and there is no issues with it I am fine using it. Now, when you installed the sealant on the outside you just covered/brushed on the edges? Let me know just curious.

Not sure were to buy. Any oldtimer will know what it is. Used to make the old cork gaskets stay on the heads of cars when doing valve cover gaskets. When the plugs are pounded into the carb the metal is pushed out to make the seal with the carb the cement is just to be sure air will not leak in. I had my carbs off five times before I rebuit them the way I should have. People on this site walked through it and they run great.
