Spark plug gap

[deathegg]

Hi Everyone,
Well, I'm getting new plugs for the DeathEgg ('88 L+) tomorrow. I see in my manual that the gap is .0390 - .043.

Not a big range of adjustment, but has anyone experimented, or just happened to notice, any difference between setting the plugs at the minimum or maximum gap? I usually just set them to .040, but would be interesting to see if there is a benefit to setting them differently this time.

I set them at the low end as well, so when they "burn open" your still within spec.

Theoretically....the bigger the gap the better the ignition of the fuel and a slight advance to the timing....also takes more goil to ge the arc to jump. The smaller the gap the the harder to ignite the fuel and a sslight retard to the timing.

0.039-0.043 does is too small of a range to make a difference.

Most important...they are gapped the same.

Just gap it with a quarter!....j/k

I run NGK plugs gaped at 40,works for me!!

[FestYboy]

i run everything at .036, never an issue...

I use whatever comes on the spark plug gapping tool.
The only acceptable gap on the tool I have is 0.40.

Not meant to be. Joe puts out some good advice. I just happened to agree with the part of it I posted.

OK!:p
Just that I'm forever forgetting to use "not" or "can't" in my replies so I generally let things go like that.
You are correct Joe provides good data and is one of the "go to" guys in many cases.
We are lucky we have more than a few of those kind of people here.
