No Sandor, your english is very good. The nipple protrudes further forward than the former, maybe I have got the retracts too far forward. I am having to attack the actual spruce bearer. Now, when I got the retracts off Ali there was no risers in the kit. He then sent me some plywood 8mm thick, I am wondering whether this is too thick resulting in the cylinder not going deep enough therefore fouling the bearer. This make sense to you?
