The Nv40 on outside looks std. But it is the gas burning glow ignition. I have had it a couple seasons and have not tried to run it yet. I plan to this season. The other I just got is a spark ignition gas burning 9cc ngh. Both engines I have read reviews from one extreme to the other. If they can run good I usually can get a engine dialed in. Other pic is some of my engines waiting to get in the air again someday.
