THANKS, Noco! So much info in your reply, now we just have to figure out how to apply it. An air leak sounds likely. "We" will check that out. Haven't done anything about the coaster break YET. He really gets "SHOOK" by the problems. It was pre-built, and he's kind of "timid" about working on it. (Doesn't necessarily "trust" me to do so, even tho I've figured out how to "fabricate" answers to some "minor" problems. (chain guard breaking at its front mounting and rear mount being tweeked out of shape by it, etc.) I was a fencing contractor for 15 yrs., and am mechanically inclined. I think it is ME who could reall get "into" the bike. He just wants to ride it. I LOVE this forum and the things everybody has to say about these way cool bikes! Chain length . . . bike was pre-fab so assume it was cut right. Have NO clue what size it is. Tire allignment . . . He hasn't even let me check it out! (OR "play with" setting the tensioner!) He took it to some friend who told him that 8oz oil/gal of gas was 20/1! The info you just gave me makes PERFECT sence! Now I just need him to let me get my hands on it! The tire itself . . . I have no idea about it's size. Bicycles were never "my thing". I never paid attention to the "basic workings" of one before. That leaves me behind the curve in even the basic bicycle mechanics of his little "black beauty". (MY affectionate name for it, he just calls it his bike) But thanks to you, and all you others, I'm able to at least work toward understanding. I would send you a picture, but I don't have a camera that will load to my computer. Must be time to get one. Will do that and as soon as I can I'll post some. At this point, I may not be posting until I can figure out and APPLY the info you've already given me! I will still be following the forum however. I sure do thank you for all your help so far, and "I'LL BE BACK!"
