Engine Acting Up When cold

Hey

My b2000, doesnt like starting and idling when its cold.

Even with the choke, it pisses out black smoke and sounds like a rota.With out it, it just dies or doesnt start. When your driving it feels like its missing hard, and only really drives well at high revs

I was living up a mountain for a while and it was acting fine, Maybe something to do with the altitude.

Any help is appreciated

Cheers

let it run for a good 5-10 minutes and use and octane boost cus ive knowticed thats helped my idle on startup

Sounds like something is gummed up. spray some carb cleaner in there. Just follow there instuctions.

True, could be something gummed up in there, Carb Cleaner, where abouts are you located?
