I just bough a use craftsman hedge trimmer 21 cc weedwacker (model c944517360- 16 inch.) and i'm looking for fuel mixture for this 2 cycles engine. Waiting for the info ... I'm trimming right now and i'm out of gas ...
2 stroke engines run between 50:1 and 25:1 oil:fuel ratio. Running with too little oil could possibly lead to engine seizure, however, running with too much oil, the only side effect is a little extra smoke. So if in doubt, run it with the stronger oil to petrol ratio and you should be OK.
