You had a look for that pipe yet? My old gas start Wrens were really inconsistent starting till I spoke to Mike at Wren. Seems the pipe was there to protect glow element but ended up shielding it from the gas. Only later versions it was moved away, but Mike instructed me to gently use a screw driver to ease it away from glow plug opening, After doing that, they both started first time on the gas. I used OS 4 stroke plugs with element teased out.

Looking into turbine through glow plug hole, can you see a small diameter pipe running across the hole? If so you need to gentle tease it out of the way.
I was nervous sticking anything in my turbine, but Mikes advice was spot on.

I've talked to wren and they can change it to kero for me for not a lot of money. I am very tempted.
I've had a 54 before and never had this stress. At least they will run it and set it up when they do the kero modification's.

Funny, when I spoke to Mike he offered the same thing, but said it was a waste of money as it should start perfectly on gas. If you've tried everything then there must be something wrong which needs an expert eye to sort out.
No harm in changing to kero start, but if you have other gas start turbines I'd just get it sorted.

”...change it to kero........for not a lot of money...”
well, maybe: depends on where you live UK, EU, USA and what ECU that you have.
”....Xicoy/Fadec ECU V10 AU107/108K...” required otherwise you are going to have to get a new ECU as well.
For a kero start upgrade = £146
New ECU & HDT if needed = £167
Total £313 or $421.80 USD at todays exchange rate.
add in shipping costs both directions (maybe $80USD) as well as your banks fee ($45 in my case) for international wire transfer of payment. (They DO NOT do PayPal)
real total = ~$546.80 not exactly “not a lot of money” if you are in the USA.
Anyway, the above costs are why I am leaving my Wren Supersport with propane start.....

An video will help a lot in to quickly troubleshoot the issue. Usual problems with these engines is that the power to the starter is set too high, blowing the gas off and preventing the chamber to heat up in aft to allow the kero to vaporize and begin to burn. Next time, please take a video and post.
