Which electronic ignition?

Question, after you upgraded your ignition and coil did you find it necessary to open the spark plug gap?

 

Straight from the horse's mouth:

 

It also depends on the air-fuel mixture; the leaner you go, the more gap you add, the richer you go, the less gap, both changes are over stock. And, of course, it's trial and error, I would recommend a few sets of used plugs, all gapped over or under stock as the case may be for your engine and when you've found a good-performing gap, put a new set in, gapped .002" smaller than that gap on the used plugs.

 

I did not change the gap at all...

 

Do you have pics of your plugs?

 

No, I don't even have my chero yet. There were covid related delays in the shipping. But it's finally in transit. I'm just knowledge gathering right now.

 

Ah, OK.

 

Dura spark is good into low 10s
