Well the problem is i screwed up.I had 2-[23.6] that i was going to use for an echo[bme] twin.
Then all of a sudden they where all gone.
So i needed to pay a couple bills so i converted them,put on an rcxcl ign,and sold them.
Now ive just come across a bme twin case after 1 year of waiting.
Now i dont have my engines any more.
Oh well,ill keep looking.
