I rebuilt my Webers, tuned them and installed new front springs from Center Line! No better way to get to know your Alfa then working on it. VERY pleased with springs, the ride is MUCH improved. The springs went in VERY easy. I used the 6 bolt, all-thread method. Re-installing was faster then removal. The new springs are so much shorter then the old, most of the nut turning was done without tension. The Carb rebuild wasn't as bad as I thought. Good resoures on this board for both projects!!!
