That's very odd and must be design related. NST's love blown gaps to 2KW

Just thought I'd throw in my 2 cents worth, since I just tried this-
Someone earlier mentioned that a single gap might be better than an RQ type,
that was not the case for me. I'm using the blower from an air hockey table
quenching. I temporarily replaced my multi-gap with a single gap, fixed in a
large pvc reducer fitting (I think 3" to 1 1/2") and directed as much air as
possible over the gap. Cranking it up to about 60% power, within seconds I
watched the streamers get reduced to almost nothing. Shut it off, let it
down, and the same thing happened. So, for myself, I'll stick with the RQ
