I bought a 17057253 carb off of eBay, it came with CV secondary which seems to be the correct rods, however it appears that the rods are bottoming out on the factory plug before sealing that silver disc, is this normal?
Also, if anyone could tell me if I would have to increase the Jets or idle tube size. This will be going in a 72 cutlass 455 manual, 12mmg vacuum, 9.5:1 compression, cam lobe separation 110, @50 230/236
Thank you!
