anyone have reviews on this product? http://www.summitracing.com/parts/HLY-64-7779/ I'm looking to replace my 750 BG speed demon carb, and was looking at the holly rebuilt rochester qjet another option was http://www.summitracing.com/parts/HLY-0-4779C/ as this one looiks just like my BG speed demon and will most likely use the same fuel lines side note: I want something cheap and be reliable..wont give me idle(Speed demon jets too big?)/ hot start(probably too much timming), and secondary problems(seems to suck air at certain rpms and never seems to open) like my speed demon does! I'm also wanting cheap as I do plan to replace this carb with a blowthrough CSU when i do get my twinturbo setup installed thanks in advance guys!
