The manual probably says 40:1 (3.2oz.oil to 1 gal gas) but if you use a good modern 2 cycle oil,50:1(2.6oz .oil to 1 gal gas) will suffice.

sounds like the tension spring has broken. remove the cover on the pull rope and look inside the rope coil, the spring is located under this.

Hello:

Have you Removed the Muffler and Checked the Exhaust Port and Muffler for Carbin Restriction?
Remove the Muffler and Start the Unit. If the Operates Correctly, then the Spark Arrestor Screen is Clogged and the Muffler/Screen Requires Replacing.
Make Sure the Exhaust Port is Not Restricted Also.
Hope this Helps.

Good Luck

One suggestion, unscrew the spark plug and reconnect the high voltage wire. In a very dark area move the plug so that the plug thread touches some metal on the engine. Pull the starter cord. If you don't see a spark, remove the two screws on the handle and see if two wires are attached to the Stop Engine Switch. Remove one wire and bend it away from metal and try to see spark when pulling the start cord. If spark occurs, the Switch is shorted and needs replacing.
