I'd suggest getting your carbs from a reputable supplier that knows type 4's, and is familiar with engines like yours.
Don't get sucked into the false premise that if you don't get big carbs and venturis, you'll be giving up power. You want an optimized carb/venturi/jet package, which ultimately depends on your engine specifics. |
