I use the Fox R/C Long glow plug with idle bar as my go-to glow plug for all of my 2-stroke engines (at least .25 cu in or larger, anyway). It's an excellent medium-hot plug that performs well in a wide variety of engine brands.

If the idle bar is no longer necessary, as other posters have suggested, it has also been my observation that idle bars certainly don't hurt anything, either. I've seen a great number of different 2-strokes respond wonderfully to the Fox R/C Long plug.
