Spark plug gap for standard NGK in DA-100?

Anyone know the standard spark plug gap for the DA-100 standard NGK spark plug? I figure around .25-.30 but was wanting to know for sure? Anyone?

Thanks....................

I have 2 DA-100 manuals. 1 sez .015"-.020" and the other says .018"-.020".

The best answer I've heard is that a #11 exacto blade is exactly the right size.

.018 is the right number. You can go down to .017 but for our purposes .018 is the one.

Re: Spark plug gap for standard NGK in DA-100?

Hi!

It reads in a NGK CM-6 plug package that the spark gap is set to 0,4mm.

I measured one and it is exactly 0,4mm. That equals 0.01575 inches.

Atleast DA-50R uses CM-6 plug.

What are the effects of slightly adjusting plug gap to a bigger or smaller gap?

larger gap, bigger spark. Smaller gap, littler spark. Too small a gap and the spark will be too weak. To large a gap, and you may get misfiring or intermittent firing.

Will a gap of .016" be too small?

18-20 thousandths I think is the recommendation.

And sometimes the X-Acto blade is stuck in my finger, so it's really easy to find.
