1982 QT50 need control unit please !!Help

[martman]

Heres is what I found now !

When I start my QT50 (with the key in start position) once the bike is started I can run it in start position or run, there is no change !

But I dit check all my connections and when I play with the 4 wire on the Control unit (the one under the seat that hold in place with a rubber band) and the key in start position...it does bogg down and act as it will not run faster and shut down.
Now I am guessing that my control unit might be defecetive...Problem is that there is 2 Control unit made that year (1982)
My bike VIN is 5x0-000254
what I have deduct is my control unit part# 4Y9-85590-M0-00
NO MORE AVAILABLE.....no even on E-Bay !
Is there nayone that have tryed a different control unit, will it work ?
Thanks for your output !
