Hello Tom
As a newcomer to the gas engine section I had a pretty hard time starting my new ZDZ 80 twin. It never wanted to start and I already thought there would be some carb problems. Now, after having had some instructions by my local dealer the engine starts after some few flips. What you should never do is priming the engine like we are used to do it on glow engines. The carb/pump (Walbro or Bing) sucks fuel/gas in the carb by itself and more priming is definitely heading for troubles!
Starting procedure:
- close choke, full throttle, ignition on
- turn till it 'plops'
- throttle to lowest position
- open choke
- turn and it will run
Best regards, Daniel
