New Motor Fired Up... help question

[Posted]

So, I just fired up my project. After working on this thing for 3 months it was finally time. All new electric, motor, etc.. save it for my build page. Anyway, I fire it, it starts immediately. Ran 10 - 15 seconds and stalled. I fired it up again and it ran 35-50 seconds, but was sounding like it was starving for fuel. I was throttling from the carb, and could see nothing going in.. I then added fuel directly to carb and it would not run...

So my question is: 1. Does this sound like it just needs fuel? No pumping or something. New tank also.

But what makes feel un easy was it not firing again with fuel in carb.. 2. Couldn't lose spark somewhere right?

3. Also had a little burn off coming out of oil fill spot on valve cover.. Is that normal?

This thing litteraly fired right up. Sounds so mean!!
