Looking back we usually didn't understand what these engines needed to run properly. You need Nitro to make them perform, Now days a great place to start is to use the currently available Helo fuel at about 30% nitro range
Most won't burn a gallon of the stuff so get with a Glow helo guy and see if you can buy a QT from him. A good battery that will glow the plug makes a big difference as well.
Fun engines if provided the proper fuel and a modicum of care.
