NC 30 not starting. Help please!

[batchelor]

NC30 start fine today.
Took it out for a ride.
Then it started to run a bit rough after 20 min or so.
I carried on marking my way home. It was a bit hit or miss on how it was running.
Then it stopped and would not start.
After a bit of pushing I gave it a go and started but was rough.
Anyway off I went then it stopped again. Bit more pushing.
Then tried start and started. This time I made it home.
But now it will not start.
Any ideas?

Flat battery, lights bright, check battery voltage?

Embarrassingly I had this

I had left the fuel tap on reserve! So it ran until it ran out of juice. I left it for a few minutes (allowing the tiny remainder of fuel to fill the carbs again). Then It started and ran for a bit then finally conked out (Obviously).

Please let me know if this is what happened to you as I don't want to feel like the only idiot in Kent!

Battery is new and was turning the engine over.
I have fuel in the tank. Wish it was no fuel as I pushed it past 2 fuel stations.

vacuum hose either loose, or collapsing in the heat. so, check that... :)

My mistake, engine cranks but does not fire, fuel tap vacuum issue perhaps or tank vent blocked.

Right. Update
Fuel tap checked and working
Fuel dumped and replaced with 5 litres of fresh
Carbs off stripped and cleaned
Think I’m save to say I have.
When I was turning it over it was firing on 1 cylinder.
Any more ideas out there? Please

Just had it running on 2 cylinders

Is your vacuum hose in good condition?

Be wary of flooding, or otherwise fouling the plugs. You'll be needing to take them out to dry.

Tap will flow with a hose that is "ok" but unless you can be sure there are no splits, then you'll not get enough fuel.

When you took carbs off- was there fuel in each of them?

Vac hose in good condition.
Plugs are getting wet.
