nah i dnt thrash it i change gears at like 4 thousand revs wen its warmed up wen its called i change at like 2 and a half so u think i should get a tune up aswel

4k when it's warm and 2.5k when it's cold?

I don't have an rpm tacho but in the manual it tells you the suggested speeds to change to the next gear by Toyota so if I did have a tacho I'm pretty sure I'd be changing at around 2.5k and thats when it's warmed up.

I have to have my foot to the floor going up hill and its a SOHC carby so nowhere near as efficient as a DOHC but I still get over 100kms easy from 10 bux =]

You are changing too high my friend.

Wha?

The 4K-C 1.3L I used to run in the KE70, I'd change gears at 5500-6000RPM when warm all the time and would get around 400km from 40L. I can't imagine a 4A-C to be much different... Except a 4A-C Carby is extremely restrictive towards airflow, I suggest chopping some holes in your airbox and your fuel/air ratio should even out a bit more... Therefore it would stop pumping fuel and still have the power.

Also as others have said, get the thing tuned...
