You are aware that you've got to run it with the canister upright for long enough to get the preheat tube hot before you turn the canister upside down?
From memory, the Trangia burner has quite a chunky preheat tube, so this may take longer than it would with a lightweight remote burner stove.
Yes - my other stove is a Primus express spider, also with a preheat tube so I have plenty of experience using one. With the Trangia, immediately after turning over the canister the burner coughs and splutters with the flame coming around the side of the pan.
PJ/Sweep - mine is less than a year old so perhaps this is a regression in newer models. I'm not the only person with this problem, see
this thread:
The pre-heating isn't fully enough for prolonged liquid feed + the system resonate and gives pulsing flares (though the frequency seems different for different stoves and different occasions). There needs to be a flow-back restrictor in the system (which there isn't any) to 'mute' the resonation
Comparing my two burners, the preheat tube of the spider goes over a large part of the burner, whereas the Trangia one barely covers it:
