pull start problem on hyper 7.
When i pull it to start the engine, at the begining of the pull up to 3-4cm it makes that noise pop-pop-pop that it always did(which is the compression).BUT after those 3-4cm out it just feels loose and it doesn't make that noise.I don't know if the engine is turning at that loose stage but it doesn't start at that.I must keep doing it from the first 3-4cm to get it running.What's wrong?
