Hi George,

Thanks for the response - very informative and sounds identical to my issue. Mine finally starts after maybe 4 or 5 attempts.

Can you explain your comment

"A friend applied a vacuum to the line and “pop” it was cleared. We don’t know what came out, but I suspect some residual braze inside the burner feed tube or swarf from the burner solenoid valve moving downstream and lodging itself inside the turbine. "

What did you use as the 'vacuum'? And was there an audible 'pop'!? Also, I take it you mean you fitted a 3mm line to the turbine festo fitting and applied the vacuum to that line to remove a blockage from inside the turbine?

I will certainly bear this in mind but I think my issue is fuel pump voltage as disconnecting the 3mm line from the turbine and doing a start sequence shows little to no fuel dripping out of the line - this would mean little to no fuel is even reaching the burner (although a blcokage would compound the issue!)

Rgds,
Mark
