I personally like my pump gas N/A cars in the 12.5-13.0 range for power and safety..
I see that, it's like everyone has a different opinion on what the ideal plug should look like ha. I will eventually buy an WB o2 when I get some money, but right now I'm stuck trying to read plugs and timeslips.

Your plug heat range looks a little too cold

read plugs

"The white porcelain does not indicate jetting !! Do not look at the porcelain
insulator for jet changes ... instead look at the plug's base ring"

I've seen those pictures before, but not sure if they're good to go by or not. I can't get any color at all on the threads base ring.

I read about a cheap way to make a O2 setup.

You get a Normal O2 sensor, then hook a multimeter up too it, and use the voltage to tell you were in the A/F range you are.

Does that really work? like a wideband? I know I'm in the ballpark. Now I'm just trying to fine tune.

I would think so. I have a feeling a pre-built wideband uses normal o2 sensors.

I read about it here- http://www.bob2000.com/carb.htm
