Small Engines (Lawn Mowers, etc.): Sentry Rototiller, rototiller, bridgers

Question
QUESTION: Dear Mr. Bridgers: I am trying to configure belts on a 1975 Sentry rototiller it is equipped with a 3.5 hp B&S engine. I do not have the manual it is a model 200-D.  I'm not sure if the belt in the tiller is the correct belt, although I am assuming it is. After running the tiller a few minutes the belt starts to smoke and when in neutral the tines keep turning. Either I have the belt wrong or it is too small??  Do you happen to have a manual or know where I can get one?  If not would a picture help? The engine has one pulley and there are two main pulleys towards the front of the tiller with various other pulleys and tensioners. I know this is vague I can give you more detail if needed.  Thank you.
ANSWER: Hello CJ:

If you can Post Some Pictures Online for me to View, that Would be Helpfull. I am Unable to Locate this Model in the Murray Manuals for 1973 through 1977. Are there Any Other Numbers on the Tiller? Thanks.

Respectfully

John
