NEED HELP ASAP B2000 wont rev

i have a 1983 B2000 and was driving it fine the other day when suddenly it just started to die and eventually got so bad that i had to keep stopping, i think it might be a fuel problem but im unsure any help would be great.

make sure your not jumping time. these trucks dont normally break down or leave u stranded unless somthin stupid happens. hope its somthin simple.

ok i fixed it, it must have been a problem within the carbi, cause i put a different carbi on it and its running dreamily now

hell yea
