Hydraulic problem on mast operation.

Toyota 8FGCU25

When raising mast the 2 outer cylinders have started to lift first before main center cylinder.
Sometimes the main cylinder will start to lift first about 20 inches then stops and 2 outer cylinders will start going up.
Forks do not creep down when left up off ground.
What regulates the cylinders to make main cylinder lift first.

I had a similar issue on a Clark. Ended up being a Cushioning valve.
