I have a 2166 with long feederhouse (60") and added a rocktrap. I cannot seem to get the 1020 head to cut close enough. I have rocked the face plate as far forward as it will go, but still not enough. I know that machines with a trap have the short feederhouse, but I think this should still work. I took out the top bolt in the slotted hole to cheat it forward a little more and it seems to help. Has anyone done this and just how much more do I need to go? Thanks.
