Venturis and jets are relatively inexpensive items. I kept experimenting until I found a combination that works well for me. Type IV's have different cams, displacement, combustion, bore and stroke etc. Try a combination of jets and venturi's that work for you.

Know that well from years of fiddling with carbs. Thanks.
I should have been more specific: for a totally stock 2.0 engine, what carb/venturi/jet combination seems to work best......? Hoping there were those who knew what works best with everything else being stock. Of course, I know there will still be widely varying opinions - such is life. Just wondering if there is a consensus.....for a stock 2.0...... GN QUOTE(Elliot Cannon @ Oct 13 2017, 07:16 PM)  Venturis and jets are relatively inexpensive items.
