80 gl 1600 bad milage now won't idle

[mikaleda]

i just bought this car not long ago so i don't know alot about it. it is a 80 gl 1600 ever since i have bought it it has only gotten between 20 and 22 mpg it has the stock carb. i have driven a couple tanks of gas through it and ran some carb cleaner through it and it still isn't getting very good milage. now it refuses to idle lower than 2k anything under that and it will die and if you are driving under 2k it will splutter and have loss of power but anything over 2K and it runs good. i adjusted the carb before this started and it ran fine for a tank and a half of gas.

 

there is a half tank of gas in right now so it has gas

i have never let it run out of gas.

it has a new fuel filter 2 tanks of gas ago, and yes i changed the fuel filter before i ran the carb cleaner through

the carb does look a little iffy i was thinking of rebuilding it later on

 

i think it has to do with the carb, i'm thinking maybe idle jet or accelerator pump

 

does anyone have any tips or tricks i could use to do a quick fix so i can use it for a while? i just spent all my money on shocks so it needs to be cheap.

 

any advice would be appreciated.

i had a simmiler issue with my ea-81 and my mechanic said that the fuel pump was putting to much gas in the carb and flooding it out and thats what caused mine to rough idle and die

weird i wonder what would cause that? i ordered a rebuild kit and got carb cleaner and dip i'm going to rebuid it and see what happens.

 

edit: i think what your mehanic was talking about sounds like an accelerator pump issue? i'm not sure but i know i had a toyta that had a bad accelerator pump and it would flood the carb out and a local mechanic put a b.b in it some where and closed it off and it worked for along time.

does anyone know if you can do something simaler with a hitachi?

sorry it's been so long without an answer i replaced fuel pump (the one in the carb), needle and seat, and gaskets cleaned out the inside of the carb with chlorinated carb cleaner. it worked! now my car is running good again. i am still am not sure of the mileage i'm getting other things have been breaking and i haven't ran it enough to know yet

my brat got about the same mileage when it was still driving and not parked to wait for my dad to help remove the motor with a forklift and put the jap import back in (i can put the motor back together by my self ive done it before same with taking it out) i think these things can get anywhere from 18-30mpg but im not quite sure on those numbers so dont count on it, my dad had a ea82 dual range 5 speed and it had the lower gears in it thats factory (very rare) and it only got 18-20mpg not very good but it was a beast in the snow:headbang:

i should get around 30 mpg because i am running 185-80-r13 taller and narrower tires than stock and i have the 1600. i just have to figure out how far my miles are off per tank because the tires changed the gearing which means my trip meter is not accurate anymore.
