Are you sure your idle ports ( size of pinhole) in carb aren't plugged with something? What happens if it starts to die, and you give it a quick squirt of WD-40 , down throat of carb?

i would check fuel supply, volume adn pressure, i wold also look at the MAF sensor hot wire to see if it has a little chia pet growing on it.

There should be one screw (I'm assuming it's the Carter YF carburetor 1 barrel) that's by itself away from linkages etc, more to center at base of carb where it meets manifold, that is angled approx 45 degrees going in to base. That should be your mixture screw. What symptoms are you experiencing anyway?

I would check the oil pressure of the engine. The reason is the timing chain tensioners are run with oil pressrue. I think your timing chain tensioners are leaking down when engine is getting to operating tempature . The oil is thinning down as warms up , as it should to lubercate . I would check compression and do a cylinder leak down test on all the cylinders. Then if the compression is good and the cylinder leak down is good. I would change all the timing components, ( chain, timing gears, timing chain tensioners )
Good Luck , I hope this helps.

Please check your idle controller whch is normally located near the air intake.Sometimes cleaning them and putting them back solve this problem.
