I'm interested in the B3 and I think I have a nib .12 SG engine at home ... problem is I just moved and it'll take some schlupping around to find it. If I can find it, it's the Yokomo 12 that came with the GT, slide carb, nice porting on the sleeve ... I got it to put in my Ofna OB4 pro but couldn't figure out how to get an SG shaft to work in it so it's just been sitting. Non pull start. I'll look for it tonight when I get home from work. -John
