Samurai stalling at junctions/stops

The wet foot well might be the air intake for the heater filling up. Try poking something up the two little right angle drain pipes in the engine bay to check its clear.

I'll second that

They have stupid little flaps that keep the shit in.
Well mine used too

Tried approaching a stop but knocking it into neutral and coasting up to it, doesn't die until I start braking and just nearly stop.

Would a leak on the servo diapham cause this
Are your brakes working fine
You could try capping the pipe at the servo and see if this helps.
Please bare in mind that your brakes will be rubbish if you try this, so only try it somewhere safe just to test it.
This is only a thought so I could be completely wrong.

Though id write here if this would be a help for others.

I had this problem that the SJ413 (G13A, original carbruretor) would not idle when the engine was on normal temperature but when cold it idled. Checked the carburetor for air leaks but nothing helped.
Checked the float (bended a bit upwards) and replaced the main slow jet (original seemed to be a bit oxidated and possible clogged) and after that it idled normally when hot.
