When I was,, sort to speak,,guessing & reading plugs if too lean or rich,way back when,,one way I would check the cruising circuit,I would have the engine turn about 2000-2500 RPM range in neutral & hold it @ that RPM,if the engine was too lean,the idle would go down a bit & seem to run a bit rough.
Doing it this way,you do not need to drive your vehicle all over the place,change jets & drive again. (Saves time)
That was one of the best ways to check if your too lean on the cruise circuit(lack of proper terminology),@ least it was for me.
Hope that made sense
Now I just check the A/F ratio w/my LM1 from Innovate.
I also purchased an LC1 on Ebay,cheapest I found anywhere.
The LC1 is a set-up that stays in the car you want to keep it in w/a gauge to read."A stand alone kit"
Here is the lowest price anywhere & I got it even less than advertized.
