i recently bought my luv after owning one 7 years ago an selling it i bought this one for a daily driver to work and back and to take on the occassional hunting trip... after getting on the highway and getting the truck home when i pulled in the drive way it sounded like the throttle was stuck its idle was what seemed like idling very fast... the next morning i drove to work and when i pulled up to work it did the same thing i adjusted the idle screw and then it wouldnt idle in the morning... i dont have a tach so i dont know exactly what its idling at... after a few days of driving i kinda gave up on it but would like this problem fixed... i have also had a problem the pevious owner added an after market electric fuel pump with a switch i accidently left the fuel pump on and had a huge mess to clean up... after changing the oil and letting the gas evaporate i then fired the pickup up and had the same problems... i tried adjusting my timing and carb but without knowing my idle and everything else it is extremly hard to do... if anybody has ne idea i would "luv" to trouble shoot this lol... it has the stock hitachi carb on it and im thinking the choke maybe my problem i have just ordered a weber 34/34 and plan on replacing the carb with this... if neone has any other ideas as to what i can do to make this thing like a champ again im ready to listen thank you all andwill be ready to show my pride and joy off to the world

First thing I would do is fix the fuel pump problem first. Wire it to the fuse box or find a wire that is energized when the key is on but naturally dies when the key is off. I don't know how high your engine idles but you seem to be on the right track. Maybe make sure your air and fuel mixture are good first then try adjust the idle. Maybe add a stronger pull back spring to it. And also your timing as you have mentioned. Make sure there aren't any vaccuum lines disconnected anywhere. My '79 idles perfect but my '81 idles a little high, I can kick it down but it will eventually go back to a bit of a high idle. It's getting better than 28+ MPG so I am going to deal with the high idle. Good luck and keep us posted. If this is your first time out here on the site....Welcome!

thank you dog i did wire the fuel pump into an acc wire and it is no longer a problem i appreciate the response

Mine was doing this so bad it ws overheating truck found out after ALOT of trouble shooting it was my distributer cap! The clips that held it place went bad so it would move causing it to rev way higher. Other than that sounds like carb.

well after replacing the carb it fixed all my problems til............ last week i threw a rod.... ugh now to fix it !!!!
