I would like to use this thread to thank lior (I3DM) for all his help.
the RAM500 in mine and, as lior said, used to worked perfectly.
after a few month of sitting on the shelve, i decided its time to put it back into action.
the turbine started perfectly but didnt worked that great, although it did idle fine, it had problems reaching the maximum RPM and puffed through the entire mid-range.

talking to Carlos, we decided to take the turbine apart and found two blocked needles.
warming them up and burning the dried up oil that clogged them solved the problem.
as for now, the turbine works good throughout the entire range of operation idle-mid-full, but it just wont start with the glow plug nor spark plug.

I would like to thank Lior for all the time he spent in my workshop so far.
it sure is a good thing to have such a good mind, good hands and a great friend for help.
Lior - thank you my friend.
