Well it started spooling up and reached 32000 rpm with the Kerosene trying to ignite
(pump start Auto+0, ramp 004) but it didn't made it as usual.
During cooling the starter motor gave up.
I just tested it and the fadec is fine only the starter motor is burned.
Looks like 8 cells are much so i will try 7 cells later.
Maybe that was the problem all along, the starter motor failing gradualy.
That would explain the easy first start, the more difficult second one and the failed third yesterday.
Anyway i ordered a Permax 280BB for the starter motor as i heard that it is the best for the job.
The Fadec manual also states that if the engine does not reach idle and the temperature is excessive
then replace the starter motor or the battery or incease number of cells.
Btw i checked the fuel lines and everything is running freely and bubble free.
When i prime the pump the excess fuel that goes to the engine starts dripping
after a while from a screw in the front of the compressor, is this normal?
(it runs between the outer steel cover and the engine casing)
Anyway if the motor is not the problem then i guess that something is wrong with the CC or fuel injectors
as i cannot find any other problem and friction is very low.
So finaly here is my new set of questions:

1) How much does your motor last? I read somewhere that the Wren starter usualy lasts 3 starts before it dies.

2) Any ideas on how to remove the bendix clutch without any special tools and what type of motor is
used for the starter motor?
UPDATE: Heating with a blow torch, two screwdrivers and a drop of blood from my finger
instantly removed it.

3) Could i have damaged something in my first run using 7% oil or blocked any fuel injectors or something?
When the engine reach ~30000 rpm and it doesn't increase rpm, i hit the throttle cut switch and the
engine spools down very nicely with no friction.

Of course please remember that i am not asking like you should have the answers right here and right now
but i am just trying to find my way...
