Thanks Jim👍

Here's a quick run down on how the Hi Speed works: belt driven pump off the engine, fuel volume/ pressure increases with rpm. Idle Bleed, Hi Speed both open at a set psi and then also incorporate a jet in order to bleed off fuel. An engine in this case needs a plenty of fuel up to max torque and then needs the Hi Speed to bleed off fuel. If it didn't the engine will drown in excess fuel.
