Default Starting problems with RAM 500

Hello guys,

My buddy has a RAM 500 which was sitting in storage for a few months, and when we started it 2 days ago, it was working well in idle and full, but poofing and cutting in the mid range.
We talked to Carlos from RTI (great guy and a real expert of his work!) and he advised we probably have a clogged needle or 2.

Since we wanted to fix this quickly, we took the engine apart ourselves and sure enough - 2 clogged needles were found, and cleaned - now working well.

When we put it back together, the CC was slightly off its position when viewing through the glow plug hole. we didnt notice this initially and tightened the glow plug anyway, which shorted and burned of course.
After pulling it apart, we found the problem with the CC being off position, took it back apart and re adjusted the CC - and now the engine doesnt want to pop the gas no matter what we do.

Spoke to Carlos, he advised moving the gas stick one stick to the right when viewing from the back of the CC (overall 2 sticks right from the glow plg stick) - did that - still no joy.

Since we thought about a possible ECU problem, we tried with 2 different glow igniter independant fromt he ECU a- and still no pop. we can only start the engine by igniting the gas from the tail cone with a torch.

Now, we are looking for ideas as to why it doesnt pop - we tried several OS 8 glow plus (all with pulled coils) and no joy. we also tried a Forgeus Research spark ignition system - still no pop !

Two things i did notice:
1. the CC might have been slightly "dented" inwards around the glow plug hole from the first mis alignment / plug tightening. this creates a garp of air between the glow plug sleeve and the CC.
2. the sleeve in the case which holds the plug rotates slightly when we tighten the plug - it is slightly loose.

Any ideas guys ?
