I just tryed to start the engine in my garage, so I did'n blow anything else!
Well, I'm assuming the engine is gone because before I started, the engine could be rotated manualy without the glow plug smoothly.I connected all fuel tubes as required, turned the engine manualy holding the finger over the carburator to suck fuel inside,pluged the glow plug with medium heat and started.It didn't work for couple times and finally started, running the engine for about 5 seconds and stoped.
While trying to rotate the engine manually again(without the glow plug), I could notice that there is one point where the engine gets stocked, really hard, even making an terrible metal to metal noise.After that, I placed some after burn oil inside the glow plug to see if was missing lubrification, but the problem is still there.
I called the store where I bought the stuff and the guy said this is normal, but I don't think so.Am I wrong?
