Sounds like you might have flooded the engine to the point where it is liquid locked. There can be so much fuel in the cylender that it wont even turn anymore [:'(]

A pull start engine is very easy to start, you should not need the bump starter.... You just need to learn how to start it, be careful not to flood it...

Are you sure your glow driver is working ? Try it on a glow plug and make sure you see orange glow....


If it is not liquid locked, maybe to lean ? If it turns and turns , but never fires, you need to prime it, a few drops of fuel in the carb will do it...

From the Hobby shop test, The engine obviously works very well, you just need to figure out what you are doing wrong.
