I think I still need to size up the pilot one and go just a little less on the spacer but it's nothing urgent. Saw a carb on eBay like yours with a filter that I was tempted to buy but I'm just a little to cheap. Especially since I just put in the K&N for $45.
You could try the 55 pilot jet but I'd leave the spacer alone at this point. You might even consider trying the 155 main jet for a while and see what you think. Overall, you're probably pretty close right now.
