Engine ran tonight

So i did a few things and got the engine to run for 30 minutes :

- cleaned the plugs

- redid the setup for the timing and breaker gap, one of these is probably what helped although the tachmeter I bought is giving erronous readings so it's tough to check correctly. But at least i have the stroboscopic light and i can take readings. From unplugging the vacuum tube it looks like both the weight and vacuum advance are working. I am reading 28 degres on the flywheel at around 2 or 3000 rpm, is that too much ?

- After much time trying to start with every combination of the chocke I could finally get the engine to start properly and move on to try to setup the carbs a bit better and that's where i could not make sense out of it anymore.
First my idle is high and on the left side even with the idle screw out it was still high. So i wonder if that's due to an air leak or the mixture ?
Then adjusting the jet nut on the left side made no sense, whatever i did (tighten or losen) the engine would still slow down when i lifted the pot.

At least when warm the engine would not die anymore like it used to when i accelerate.

Got a few actions to do this week :
- ask the excellent triumph experience forum for some ideas
- looks at the plugs, between the front or back ones and see if some are black
- see if the engine starts easy like it did when it was warm.

There is hope !
