Hello guys, I am a newbie and found this site trying to ID my mini bike I just bought. Turns out, after much searching.....I bought this mini bike in this thread. I really like it but want to find out what it is. I agree it looks like a modified Bird but the seat is home welded and the springer front end looks like it was home fabricated as well. Regardless I want to find some parts for the engine and a year. It is a craftsman serial and model number 143-614032 1084B which crosses over to a Tecumseh ECH90-146006A. On all the small engine sites I can find 14600
5A and 14600
7A but no listing for my numbers. My question is: Does anyone know what year this engine is or what might be the same specs as mine?
