Colourtune and spark plug condition

Still looks a little bit rich to me. Especially no 3.

Agree looking forward to take them out tomorrow, I hope I don`t have to high RPM back and forth to work... try to not go over 3...

I don`t see big difference...

I have adjusted more out:

Cylinder 1: 1/2 out
Cylinder 2: 1/4 out
Cylinder 3: 1/2 out
Cylinder 4: 1/8 out

Picture below is before I was turned out according to table above. I have now inserted new spark plugs and not cleaned one.
I need to wait some days to see the results, need to fix the threads on spark plug 2 first...

Just installed an A/F gauge. Used a gauge pod and a generic mirror bracket for mounting. O2 sensor is underneath after the collector where it can't be seen.

New spark plug and back and forth to job again... tried to keep it around 2rpm not up to 3 these time....

What do you think?

1 = Is good ?
2 = could be some better?
3= to lean ?
4 = to rich ?

I have not any new spark plug now, so need to clean them best I can....

1 & 3 look pretty good to me. 2 & 4 still look rich.

Looks like you can dial them out using the pilot screws.

I cleaned the spark plug today, please see picture below, it was to hard to get them to look as new, but hopefully is it good enough....
I also adjusted the air screw some out on the carb. who was to rich... with my stomach "feeling" based on the look.

Will try to take a short trip tomorrow or Sunday and keep the RPM under 3RPM.

I was driving a short trip today, please see picture below its X_6 from today.
It was hard to get the spark plug 100% clean before the test run....

I have only adjusted the 4 cylinder out 1/4.

On Friday will I go on a weekend trip, so not more adjusting right now....
I will order new spark plug, at least 8, properly 12is good to have and continue adjusting after the trip.
I`m also curious to see how the plugs looks like after the weekend trip.

as I see it has the testing improved the mix`er.
