Help reading spark plugs

rejetting Carter / Eddy carbs is NOT stright forward. the short story is you can NOT change the the Jet and rod at the same time and know what your change was, by guessing. i have a computer program that i wrote years ago that can calculate it. i have posted the link on this site some time ago. if i can dig it up ill try to post it. but my family life is keeping very busy.

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

IMOHO First thing to do with a eddy is check your vacuum and put in the proper color step up springs. If it's out of the box and you have a cam, they need to be changed.

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.
