First thing I would do is find out whether you have a motor or not. Do a compression test.
1. Run the motor long enough to bring it up to operating temp.
2. Put a tag on all the spark plug wires, identifying the cylinder they belong to.
3. Remove all spark plugs to make it easier to spin the motor with the starter.
4. Disconnect the hot wire from the distributor/coil to prevent a fire.
5. Remove air cleaner.
6. Use wire or cord to hold the carburetor primary throttle blades wide open.
7. Insert gauge line into spark plug hole. I've used the type that has a rubber tip that you have to hold firmly into the hole and I've used the type that screws into the head like a spark plug. Either will work if you follow instructions.
8. Have a friend grind the starter through 4 or 5 "chuffs" so that you max out the gauge on each cylinder.
9. Write down the results as you test.
10. Sit down and admire your work.
11. Post the results for us to see.
