The fuel on that 'short 1 second priming burst' has to flow into and through the fuel ring manifold, along the sticks drip through the CC holes and exit at your leak. As hinted by MNModels thats not right, in the sense it might leak with a loose fitting but its leaking far too quickly. If it was only at idle or running you might see a pressure leak there at a looose fitting but at prime up, certainly not right.

My reasoning for the next run was if you started with 'fuel ramp 2' and got some kind of ran up then go to 'fuel ramp 4'. The guys here rightly would expect the default setting by Gasper for Joe on the CMOS sram memory 'data hold on power off' to be a setting of 'fuel ramp of 6' and some successfully use a 'fuel ramp 10' but if you are having the suspected problems internally the higher settiings may only exascerbate the overheating problem with maybe an Over temp Cut Off or then go on to really fry the rear bearing.

Every fuel ring received has needed some basic adjustment except those from Andy the retired JJ rep. From some of the PMs to me in the last few days others have received replacement CCs from Joe with needles barely into the sticks, others the orientation of needle ends have not been facing onto the hot face and this will all add to poor atomisation and air mixing of the fuel, which effects the running and power if just left as is.

I know many wish you have favorable experience with your first JJ turbine and others may follow your lead. There is not much that cannot be resolved one way or another, so I know you will get there and its really worth it.
