Carb draining?

86?
Not one of those electronic Q-Jets?
Older Q-jets are what I run. I got a pile of them.
Take the base off. And those plug right in the middle of the body should have epoxy over them. They do leak sometimes.
But I’ve never had the problem.
If you clean them off first, and use good epoxy, it shouldn’t come off.
But you can’t put too much of a build up on it or the base won’t seat back on the body.
Might require you to file some of the glue back off when you are done for a snug fit.
There isn’t a lot of room in the cavity.
I WOULD NOT drill anything if this is what you are talking about.
(Sorry, had to be emphatic)
