Cheers for the update on what fuel your using I thought it was running to clean for diesel.

Had mine out today and got it running/starting a lot better, settings are auto +1 and 68 pump ign,k. It's very close and a lot cleaner.
I am new to turbines and was wondering if cold diesel on a cold day would be a factor, today was 12 degrees C and after a few good starts on the above settings I put it back to factory auto +3 and pump ign,k 64 and it refused to start, hangs on preheat every time so a change was indeed justified and had to be made.

Ran it three different days now on the bench and feel I have made progress each time out and have a setting close enough to use now, of course would rather it just ran out the box but it did not. On the plus got quite familiar with starting a turbine.
