Not these again. We've been down this road. A lot. I think @Johnny Mac actually did some drag strip testing. I don't remember the outcome, but I think the consensus was that if they did very much, they'd come on all new carburetors. They don't.
So the only thing I disagree with is the last part, carburetor companies want to save money and they expect us to fix their cost saving measures.. lol. So that's what the red x was for and has been removed
