I drive 1983 chevy s10 Im 17m Il
 

Hey everyone im Josh i drive what i call a beater. It has a few problems that im not sure how to address thats why im here hopefully someone can help me out.

First Problem-> Small oil leak A seal in the block isnt sealing right anything i could do besides tearing the engine apart. It's Right on the front of the block somewhere.

Second Problem: When i start the truck i have to choke it before starting then i have to keep pumping about 5cms every 6secs to keep it running until it picks up on the chok itself. The truck takes about 13-16mins to pick up on the choke itself... I dont have a clue how to fix this.

3rd problem when i first bought the truck it would Deisel when i shut it off. (deisel-make a wierd shuttering noise when i shut it off) I had my g-pa try to fix it, he messed with some things around my carbeurator and lowered something to make the truck idle lower which fixed the deiseling problem for the most part.

Will replacing the fuel pump/filter help any of the probs when i start my truck?

My main problem is when i start it i have to sit outside for like 20mins trying to get it to stay running so i can start it up. If i stop too fast it will kill it also. 55mph then i slwo down to like 25mph on the highway over a period of like 7secs sometimes will kill it.... Kinda weird...

Any ideas of a diagnoses or a fix? This truck was cheap and i would like to find the cheapest fixes but anything will do if i can get this truck running better...
