Help reading spark plugs

Cool that calculator would be pretty useful. Will alos prolly look into the 02 sensor deal too.



I have this cam in the pic, and it is pulling 14+/- at idle. Idle does seem to be a little rich based on the exhaust fumes, but that is why I put the new plugs in to see what condition my condition was in.

The step up spring is like a power valve in a Holly. Its HUGE.

You take the vacuum reading and cut in half to find the proper spring. You need the pink spring which is not what comes from the factory. It takes about 5 minutes to change them and you don't have to disassemble the carb or take it off the car to change them. Hope it helps
