i got around 300 per tank on the ke70, which was around 40L from memory (havnt filled it up in 60 months, seen as there was no engine in there :bash:)

check that there isn't a vacuum leak, the fuel atomises due to the air rushing past, if you don't have enough air the fuel will appear to drip rather than atomise.

id buy a new can of aerostart/start-ya-bastard or whatever you call it and at IDLE check for leaks mainly around the base of the carby and the intake ports

 

goodluck with it

If fuel isn't spraying a mist out of the auxiliary venturi, check that they are screwed down properly. Those screws can loosen off on the aisan carbs.

Lower the float lever

From my experiences it sounds like carby. Not sure of what, though. You'll probably have to figure it out!

i filled up 36L today so that means 36L for 250Kms?

 

you thick i should use some injector cleaner and throttle body cleaner? :bash: I'm just yanking your crank

Injector Cleaner can be used for cleaning carbies too

don't forget to check your fuel pressure regulator.

 

maybe with the twin vl turbo fuel pumps it's over fuelling the motor :)

14.4L/100km. Sounds a bit more reasonable and only out by 4L/100km....still a LOT.

does pipe fell off :) didnt check that :bash:

:bash: 6.9km/L That is pathetic. Time for a good tune and to go through everything, rebuilding the carb.

 

There must be black sooty shit all over the back of your car if you are going through that much juice. I'm surprised the plugs haven't fouled.

my stock 4K KE70 get 11l/100km which i think very very very high fuel consumption(FC)... :P

the old carb keep giving out black smoke when accelerate..

checked all spark plug, cables, everything you name it is good in condition...

i tried to change another carb(4k also) bcos i have spare one...

still the same but a little bit improvement.. no black smoke but still high FC.. =_=|||

any suggestion to reduce FC..?

no smoke during take off/idle

 

 

whould a 3k carb cause more harm then good on a 4k? aka lean out in top of the rev range?

Just head down to the wreckers and find another carb that looks as if its in good nic. even if it is a little poo, its gotta be better than whats on there now.

 

My ke30 with a 4K-H (3K head) and 5spd would usually get 600km to the tank. I do 300km/week just to and from work and would be suprised if i used more than half a tank. and i didnt drive it like a granny either.

Nah it will be fine.

 

You can always fine tune it a bit by experimenting with main jets.

 

My ke16 ran a stock 4k for a while (with extractors/exhaust). It had a ke30 3k carb on it, and I improved economy and responsiveness by dropping the primary main jet one size and upping the secondary main jet one size.

 

NOTE in the above when talking a jump in jet size I mean increments of 005 like with weber jets. So with say a 120 primary main jet, would have dropped one size to a 115. I can't remember the exact jets I used, but you get the idea.
