Who has had good experiences with the Brawler series of carburetors?

I like mine. I have a Brawler 650 mechanical secondary on my Ford truck and a Slayer 450 vacuum secondary on Vixen. Both run extremely well. I really like the extra tuning capabilities from all the adjustable air bleeds and fuel restrictors. You can really zero in on the tune. My only complaint if there is one is that I really WISH someone made sho nuff reuseable gaskets for these. Even the blue "non stick" gaskets do stick and tear. Were it not for that, I'd have zero complaints. So when tuning, make sure you have plenty of float bowl gaskets and don't over torque the float bowl screws, or you'll guarantee a torn gasket.
