Adrienne,
I think that your model is the Victa 11.38 which should be 135-638-612 or 136-638-612.
It should be a 11hp Briggs & Stratton motor but we will need the model type and code which will be stamped either above the spark plug (on metal cover of engine) or above the exhaust side.
We need more information on what is happening when you say you can't get it to start.
1. Does the motor turn over?
2. Does nothing happen when you turn key to start it?
The more info you can give us the better as we have many members that I am sure that are willing to help.
