Try if you have sideway play on the crankshaft.
There is no side play on the crank.

Sorry to disagree, but when it takes a long time to drop the idle speed, then it's usually to eich on the bottom.
If it's too rich on the bottom, you need to turn in the idle screw to keep it running and then, when you clear it out, the idle is too high and it takes a bit to load up again and drop the idle speed.
The idling is fine. When the throttle is closed the revs drop down immediately. Its only on the track when trying to accelerate from slow corners. It I keep the refs up just above idling revs, when going around the corner, the problem is gone. Its only when I get of the throttle, turn, and accelerate that this happen. When the car is of the track after the run,and I run it on the starter box when still hot the problem is gone.
I guess I will have to strip the engine completely to check if I can see something wrong.
