Carb Question

I've tried Holleys with marginal success. I've had better luck with Edelbrocks. But, I thought I'd give the much maligned QJets a second chance.
I've been reading through the Knowledge Base. One of the problems I had with QJets is they leak. One thread said to use epoxy in the wells below the metering rods.
Anybody had experience with this? How did you get the epoxy down there? Is there a special epoxy I should use?
Any help would be appreciated.

I've rebuilt literally 100's of thse things. I use Loctite Loc-weld to seal the well plugs. Just use enough to cover the plug seams.

Well, you don't actually apply the epoxy down in the wells. On the bottom of the carb, there are four plugs that seal the primary and secondary rod wells. I usually tap them lightly as to re-seat them, and then apply epoxy around them, to ensure that they won't leak.
It's good to hear you're experimenting with the Q-Jets, as they can be an awesome carb once you undertand what does what and how to tune them. Good luck with it.

Thanks for the help. After rebuilding Holleys and Edelbrocks, these seem a little more daunting, but I think I understand a little more since I opened it up. Not so scary.
