If you have a 2-stroke engine (most strimmers, hedge trimmers, chainsaws etc) you should follow the right starting technique. It is the same for nearly all small engines....
- Check you have fresh fuel in the tank ! (Premixed with the right oil for 2 stroke engines)
- Push the fuel primer bulb 5 or 6 times (if present)
- Put the choke on (if present) - regardless of temperature
- On some units, there is a throttle lock position that is applied to start the engine
- If it is a chainsaw, ensure the chain brake is ON
- Pull the cord a few times briskly until the engine pops (tries to start)
- Put the choke in the off position
- Pull the cord a few more times and the engine should start normally
- Give it a few seconds before revving or using it
Good luck and happy gardening !
