This morning I noticed fuel leaking out of the sight window on the secondary fuel bowl for my mighty demon 750cfm annular blowthrough carb. At idle the amount leaked is negligible but under throttle and boost is becomes significant enough to soak the back of the intake manifold. What is the best course of action to fix this leak? The carb is less than a year old (no backfires through it) and otherwise works fine. has anyone ever removed sight windows on a demon before? any help would be appreciated. Thanks.

They're easy to remove. Use a screwdriver with a blade just wide enough to fit in one of the slots and turn slowly to remove. There should be an o-ring behind the window. Your's may be missing or cracked. Just get a replacement at a hardware store.

thanks for the quick reply. Is the slot you're referring to on the inside of the bowl or on the outside? Mine has a brass colored snap ring on the outside. Is this what i should remove?

Oh, sorry, the windows used to be slotted and were threaded in. I guess in your case you're going to just want to remove the snap ring and the window should just come out after that. That's probably going to be more effort to put back together. The o-rings do come in their rebuild kit.

thanks andereck, I'll give it a go when I get home from work later today.
