Hey guys, i have a 1984 toyota pickup 22r carburated. Last night as i was driving it started to get hot, i let it cool down and it was fine and hasn't done it since. Once i started it back up the choke turned on and then stayed on. Also when i drive for awhile and then shut it off it wants to keep running. How do i get the choke to shut off? IT STAYS ON ALL THE TIME! CAN SOMEONE HELP ME PLEASE?

Thanks for any help
