I sent two carburetor bases to Wolf Enterprises and had him relocate the jets. In stock form, the jet in these 1-barrel carbs are located on the side wall. Under significant g-forces, the gas sloshes away from the jet and the engine is starved for fuel. That problem was a nuisance at Summit Point, but this fix should remedy that. An upside was these bases were in better shape than those previously on the car, so idling and drivability are improved.
