I got a 1980 articat jag 3000 f/c got a new carb put on it and once it starts running for about 10 minutes it just dies adn then you give it full throttle and it bogs for a lil but not idle then dies, but b4 that everythig is fine. I Have no clue what it is at all. then youlll go back to it half an hour later and it starts fine

Check for spark. Get a cheap spark tester from an auto parts store to verify your ignition system is OK. Sometimes when the stator gets hot it poops out, then is OK when cold.

Well went and started it up and there was snow on the cylinders and found otu why it was possibly running the way it was. when it runs big puffs of air seem to be comeing out of the cylinder head gasket or something. i am thinking that after it heats up it move and it just dies becasue of that, but not sure let me know.

Head gasket is maybe gone? Do a compression test and see what you get. Should be over 120 lbs.
