The manual I have for the motor says it is a 1984 if someone knows of another way to find out the exact year let me know I do not want to mis lead anyone.
The 3f I am not sure I will look though my receipts to see if I can find out for you I will post something tonight when I get home to inform on the year of the 3f
The 2f carb is from an 82 2f motor I just finished rebuilding it last month but decided to go orginal motor and carb instead
