Hey every one, i own a 74 ke25 rolla and its pretty poor on fuel economy but my dad tells me when my pop owned it that it used to run on fumes. I don't think that its the carby cos i just got a new 1 fitted and tuned and i know that the little 3k still has great compression and good timing, so if any1 has any feed back that would b much appreciated :D

 

Cheers.

Was it just as bad on the old carb?? Auto or manual??

 

Can you get some real measurements in there?? "pretty poor" and "run on fumes" is not very transferable to another car...

 

With a 4K in the Ke70 I get around 7.5 L/100km.on a trip, maybe 8.5L/100km around town, and that's on twin carbs/exhaust/hot cam. We got 6.4L/100km on a trip with the car stock when we bought it. So fill yours right up, zero the odo and run it for a tankful. When you fill it up next just write down the Km you did.

I'm pretty sure its been covered before on here, but i was thinking the same thing a while ago. At best, driving reasonably steady i get an average of 9.5 or 10L/100 km with my 4k panel van. I might just give it more stick than i think, because it is a healthy well tuned 4k.

And i know of other people getting 6-7L/100km highway cruising from a k engine.

Maybe your granddad drove like a granddad and you drive like a younger dude? :wink:
