The rack mounts I can't help much with other than to say look for one's with Japanese engines like Honda for starters. You do have to watch for things like "Honda designed"- which is a crock, or weird/no name brands on the engines.
Right now I am running a rack mount, which is 28 years old with NO PROBLEMS, other than it's pretty slow- 22 mph tops speed. It's called a TAS Spitz, they were also sold under the names Free Spirit (Sears) and Bike Bug.
The engines do all come "put together", except for mounting them on the bike, but the directions for the frame mount kits are good only for the bottom of the bird cage....that where we come in...the best directions are right here on this site.

thank you very much for this info and i remember the guy that used to tune my old racing bike always surprised me with a little gift which was a new part from japan so sounds like they are still ruling with parts... will look into the 'tas spitz', and from the sounds of things i just may need to get some help from a tinkering man so when i get an engine i will send whoever decides to help me here to speak with all of you - that way none of you will have to go through explaining the abc's to me at least 2-3-4x >> if not more lol
ps - ok am out here looking for a 'tas spitz, bike bug, free spirit' and that is a vintage motor not made anymore - yes?? if it isn't being made anymore then can you guys give some other names to check out that would maybe compare to this one because based on the little i have read folks seemed to really like that motor... thanks!
