Niva won't run

[SP450andLE]

When I took the Lada offroad a little while ago, it broke.
It wouldn't rev, and when it did manage to rev, as soon as I went to move it would cough and stop.
I have now replaced the distributor cap, rotor, points ans condensor. I have also replaced the plug leads, spark plugs a reset the static timing.
It now starts, but only runs for a few seconds, then cuts out on its own. It cuts out quicker if I put my foot on the accelerator even a tiny little bit.
Why is it doing this?!
I'm sick of it!

Sounds little like fuel starvation? Fuel pump problem maybe? Blocked filter?
Just guessing here...

Fuel is getting into the carb when I pump the accelerator, so all seems ok with that.

Coil. Only part of the ignition you haven't replaced but a very likely suspect. They break down under load and can get worse witha bit of heat. New one would be my fix

[SP450andLE]

Nah, coil is fine.

I magically fixed it! I played around with everything, and it eventually started and ran well.

Just a few more tweaks with timing and fuel, and it should be sweet.

check how tight all the screws are on your carb sometimes they get loose and move around wearing in strange places which allows air to get in from the wrong places and totally upsets your air/fuel mixture

I played around with everything, checking it all did what I imagine it should.

The float in the float chamber seemed to be a bit sticky, so played with that a bit, and it ran ok afterwards.

In fact, it ran really well considering how the plug leads on it at the moment are from my Mini...

If it plays up again, I may just get a weber carb, and be done with it...
