With half the voltage (and watts) of a #14 these should work well with most gen/engine combos. Usually I use a #131 with small engines, but they are really easy to pop if you get too heavy-handed with the throttle.

Have several boxes on order!

I hope they work well for you; these can pop with a heavy throttle hand just like any light bulb, but seem to light quicker & needing less RPM. but these are the large globe which I have found looks really good & are similar to the vintage Jensen bulb of old.
