honestly it sounds like most b series i know, unless the car acctually stalls i wouldnt worry especially since its fine after its at temp.. in addition i wouldnt recommend loosening your timing belt
I might post a vid so you guys can see what it does. If it is normal for a B series I want a new engine lol.
So no timing belt loosening hey? We did do it up pretty tight, gave the tensioner that extra pull across before torqueing up. It was tight but didn't seem too tight - there was still deflection between the exhaust and crank. It makes a bit of a whirry noise now when I rev it, but I've heard that on a friend's Honda so it could be normal.
I think the next step is to check the valve clearances again. Did a bit of googling and you get these problems if they are too tight..
How does everyone think we should do the valve clearances? We measured valve-rocker, as recommended by a few people, but when doing this the correct feeler didn't fit cam lobe-rocker. The manual for the car I have (Haynes I think) says do it cam lobe-rocker so I might try that this time. Too loose is better than too tight, for now.
Just compared for B18C. When exhaust valve-rocker = 0.007-0.008", lobe-rocker = 0.005-0.006".
Will be redoing tomorrow so lobe-rocker are in spec.
Double checked timing this afternoon, it's perfect.
Guys. Looks like the car is fixed. It was the valve adjustment. With it adjusted to spec measuring rocker-cam lobe, the idle problems are gone. The engine is a little noiser now, but at least it idles properly. I'd be looking at doing the same cb if you are still having idle issues and poor fuel consumption
