Old Loader Hydraulics Question

Finally got a Davis/MF 102 loader installed on my 1966 MF 135. The loader was manufactured in I believe the late 1950's. I don't have the bucket on yet as it is being repaired. This loader has self contained fluid with a pump mounted on the front with a shaft to the tractor's crankshaft pulley. The loader arms are raising very well. I can't tell that anything is wrong there.

My question relates to the dump cylinders. Like I said the bucket is not on the loader. The left cylinder only moves about 25% as fast as the right. Once the right reaches max distance either direction, the left cylinder picks up to full speed. Any ideas what this is? Control valve? It seems like the right is getting most of the pressure until it isn't taking any more pressure and then it goes to the left. Is it possible that is how it was designed on this old loader? What would happen if I operate it this way?

Or maybe it's because I don't have the bucket on that it is doing it?
 
There is probably nothing wrong.

Once the bucket is on they will be mechanically tied together and will operate as they should.
 
There is no problem. All that means is the right cylinder moves easier or gets fluid before the other one does. There is a T fitting between the 2 and depending on how it sits one cylinder can get fluid faster or first so it will move before the other one does because neither one has a load of any type on it
