I just went through my 2 '76 carbs on my '76 115 hp Johnson and removed the little round inspection plates to check for junk that may have collected at the Idle orifices, and, it being clean, I used Permatex Threadlocker Blue to put the new little round pieces (small little aluminum pieces) over the holes . It seems to work, but when I tried to (for the heck of it)glue two pieces of metal togeather, it didn't work too good. Did I use the right stuff. Thanks, PDS
