Looks like a Consew 227 R-1. Feed dog seems to be hitting on the back of the throat plate slot. the feed dog space from the front and back of the slot should be the same. If not, that has to be centered. If feed dog is too long in front or back, I sometimes grind the feed dog down in front or back a little. Either way, at the max. stitch, should NOT be hitting the feed dog plate. You get the feed dog centered in the throat plate front to back. Then you center the needle into the feed dog hole. Then, I check to make sure the feed dog is only 1/2" the height of the teeth above the throat plate. NO more! If needle is now centered in feed dog hole, I then equalize the walk height of each foot. This procedure correct BOB? Feed dog look long to you front to back Bob?
