I am looking into picking up a carburetor from Pro-Systems. I have done quite a bit of researching on various forums, and it seems I see about 95% (uneducated guess) of the people who actually use/have used them give them awesome reviews. Of course, like with anything, you have the 5% who had nothing but problems and bash them. If I go with Pro-Systems, I will be buying directly through Patrick and having him set it up for my combo. Please share your experiences with Pro-Systems...
