I been flying for 10 years and still do not know much about glow plugs. How
do you know when one is bad other than the engine starts running bad. The
other day I had an old OS .40 running sickly, I changed glow plugs once and
was still doing the same thing. I changed to a Tower plug and the engine
started running like a Singer sewing machine. Makes no sense to me how these
plugs work. I usually use the o.s. #8 90% of the time. The two plugs that I
removed seem to glow brightly with power applied. The Tower plug did have a
Idle bar however, I really do not know what the diff is, maybe one of you
engine geeks can explain these plugs a bit.
Thanks,
Brad
