Running rough after sitting dormant for a year

Hi all, and Merry Christmas, hohoho.

I'm in a spot of bother and don't know what to do next.

I'm out in Mexico, the v8 3.5 Defender has been sat here un used for a while. Last run 9 months previous and was fine.

I started her up this time and would start ok with plenty of choke, but then when I took the choke down, she had no power and would stall.

When I gun the accelerator she sounds ok, a bit lumpy, but when I put any sort of power requirement on it, she stalls. The choke also sticks and offers resistance.


I took the carbs off and cleaned what i could wothout dismantling too much that would require tuning, put them back on and she's a bit better, but after a few mins of running, the choke stuck again and is offering resistance (dunno if this is relevant).

When I'm driving her now, she can tug along, but the engine leaps and jerks, seems to gagg on itself and when I press the accelerator too quickly, she'll almost stall then lurch.



I'm stuck really, what are your initial thoughts? Where should I even start?!

Appreciate any help!!

Thanks

One would 'assume' that the only thing that would really suffer from a long stand would be the carbs which could have gummed.

These can often clean themselves with fresh fuel flow, but you can't beat a strip and clean.

Other option is fuel pump, but nothing else should really have changed!!
