If you want to do a static test run of your Dyan Jet engine then you need to mount it to a work bench or table. Car radiator hose clamps work fine to clamp it to a metal mount. Do not mount it closer than 4" to anything that will burn. Move everything away from the exhaust of the engine because it will blow everything off your work bench.
Check the reed valves to make sure they are in good condition. The valves need to be centered correctly there is a tiny little pencil point hole in the head that is a location device for the reed valve. Make sure the reed valve is centered over that tiny hole between 2 of the pedal valve flaps.
Screw on the head. You can locate it in any position you like it is usually best to have the air fitting on top. Screw the locking ring tight against the body.
Connect a model airplane fuel tank to the fuel inject on the nose of the engine. Fill the tank with high octane gasoline. The tank should be mounted so it is just low enough that the fuel in the tank does not gravity flow on its own, about 1/4" below where the fuel wants to gravity flow.
You need a cooling system for the engine if your going to run it very long in a static position. A good powerful fan will do the job. Mount a fan in front of the engine so it blows air over the engine from the front to make air flow over it like it would do if the engine was on an airplane. Use a good strong powerful high volume fan.
Connect a neon sign transformer to the spark plug and the metal motor mount. Plug in the transformer.
Use an air compressor to blow air into the fuel flow injector. This will suck the fuel from the tank and blow it into the engine. The engine will start up real quick about 1 or 2 seconds. Once the engine starts you do not need the compressed air anymore. You do not need the high voltage for the spark plug either.
The engine will turn RED HOT in a very short time probably 30 seconds. With out a good stream of cooling air the engine can be damaged. The reed valves may be distroyed and the engine body can crack. If you don't have good air cooling turn the engine off by turning off the fuel.
Here is a video of a 10 lbs thrust pulse jet that I built running static. I have it clamped in the milling machine vise. After 1 min 20 seconds the reed valve brakes. There is no cooling on the engine at all.
