That's quite an assumption. Maybe they only had a few in stock? Maybe a lot of people with the old ignition opted to upgrade to get the autochoke, reverse running protection (which at least the 45, likes to do), lipo capability without regulator etc.

I had the old 45GX1 before i got the GX2. My GX1 ran in reverse 25% of starting attempts. This could also be the answer to RCIGN1's questions. New technology might be needed for convinience because the engines are pusing the limits - bear in mind that the 45 is only 43cc and more powerfull than a DA-50 with 50cc. Or to dick Hanson's assuptions on why they made it - maybe they made not to get a bad reputation for reverse running, and they might as well throw the other features in there as well. Anyhow, when some are innovative, there are always some saying the old way was better. I bet it was the same going from magneto to electronic ingnition aswell.

Had the GX1 not been replaced with the GX2 (for unrelated reasons - a torn cylinder) I would have been one of those that would have upgraded the ignition, for the reverse protection alone.
