DearmanKE Posted July 5, 2008 Report Share Posted July 5, 2008 Hey guys, my ke70(4k) guzzles a lot of fuel, 10 bucks hardly gets me 50 k's anymore, in my old ke30 with a 5k 10 bucks would get me 100k's even with an amount of flogging. anyway, iw as wondering if anyone could list a whole bunch of tuneing things i could do to the motor to make it use less fuel but without too much of a performance decrease -Alex Quote Link to comment Share on other sites More sharing options...
Des Posted July 5, 2008 Report Share Posted July 5, 2008 $10 fuel these days will just fill the hose on the bowser and maybe dribble out. My Ke70 got 400km from a tank Te72 = 350km Mitsubishi Pajero = 350km from 70L Put a carby kit through it and see how it goes. Made alot of difference to dads rodeo.

7shades Posted July 5, 2008 Report Share Posted July 5, 2008 Get a weber... Much easier to tune for economy. Quote Link to comment Share on other sites More sharing options...
irokin Posted July 5, 2008 Report Share Posted July 5, 2008 I get about 550km/tank (40L). I'm still using the original Aisan carby and I've got closed points (eh... dizzys worn out). Need more info on the car. Auto/man? 4/5 speed? mods? Quote Link to comment Share on other sites More sharing options...
sammo[RL] Posted July 5, 2008 Report Share Posted July 5, 2008 10 bucks hardly gets me 50 k's anymore $1.69.9 a litre Does that answer your question? ;) As said, carby kit, and make sure your is in a good state of tune. ie timing, plugs, points etc...

chrisandliz[RL] Posted July 5, 2008 Report Share Posted July 5, 2008 My engine was running very hot, and the carby was working more like a kettle. The fuel was boiling before it was burning, I made a heat shield and fixed the cooling system and I got much better fuel use. I would start by doing a full service on the car, tuning the carby may been needed. if you have an air/fuel gauge, you could tune it yourself.

irokin Posted July 5, 2008 Report Share Posted July 5, 2008 if you have an air/fuel gauge, you could tune it yourself. (to perfection) Provided its a wideband sensor. Narrowband is an absolute waste of time for tuning. Quote Link to comment Share on other sites More sharing options...
ke70dave Posted July 7, 2008 Report Share Posted July 7, 2008 how exactly do you tune a stocko aisan carby? i thought that you can only tune the idle mixture? my car uses way to much fuel, its jsut a stocko 4k with a 3k carby. it kinda varies, with 10$ of fuel (about 6.5 litres) sometimes the fuel light comes on at 35k's other times i get up to 70k's, with pretty much the same "enthusiasm" in driving....

love ke70 Posted July 7, 2008 Report Share Posted July 7, 2008 you really can't measure fuel economy unless you fill the tank til you can see the fuel at the lip of the filler, then run it however far, and refill it all the way to the same point. thats the only accurate way of telling how much fuel is being used per a certain distance. for what its worth with a heavy driving technique i would get 10 or 11 to the hundred, and a nice gentle drive i would get 8 or under litres to the hundred. spark plugs, points, dizzy timing, dizzy cap, leads, rotor button, air filter all need to be in good condition. and a carby kit did make a difference to my economy, but not drastically. cheers, andrew Quote Link to comment Share on other sites More sharing options...
SeptemberSquall Posted July 8, 2008 Report Share Posted July 8, 2008 is the economy rapidly/suddenly changing or becoming worse? or is it just generally crap? don't measure consumption in dollars becuse your car runs on litres of fuel dollars are not a static measure becuase the price is variable?!!>? if economy has become poor all of a sudden then something has changed check vacuum advance is connected and working check ignition base timing is right check carburettor is working generally correctly, primary and secondary function etc also ke70+4k is not a fair comparison to ke30+5k ke30 weighs less 5k is more powerful so needs less boot insertion to get it around other things like tune, engine condition etc would affect it between the two packages too 1L/$1.7 per litre = 0.588L per dollar x 10 dollars = 5.8L of fuel, then 5.8L per 50k = avg 11.6L/100km, a bit heavy on the juice but not hugely bad...

dashills Posted July 23, 2008 Report Share Posted July 23, 2008 stupid question, but whats a carby kit and where do i get one? what state are you in , you get a carby kiy from a carby reconditioner you'll find them in the phone book ,but if your not that good with rebuilding things and pay attenion to what your doing if you want to drop your fuel bill a bit try lowering the float in the carby it may be set a bit high Quote Link to comment Share on other sites More sharing options...
