so i just had the head in my truck rebuilt with all new exhaust valves because they were burnt due to my truck running way lean possible causes vaccumm leak but i think it was the base plate for the carburetor it looked pretty crappy. Anyways i got it a ll back together and the truck will start and idle for a couple secs then it dies cant figure it out i was wondering if the most likely possibilty is the carburetor it seems like its running out of gas. Any suggestions would be helpful thanks.

 

did you plug the solinoid on the carb back in?

 

Give it a good spray with carb cleaner... I don't know a lot about them but it's worth a shot something might just be gummed up. Will it run with the gas down?

 

yea my truck does this exact same thing the fuel runs out of the line after so long if not starting try starting it with starting fluid to build the pressure back up

 

Sounds a bit like the solenoid to me, too. If it is plugged in, maybe unplug it & test it if you have the equipment.
