Based on Pat's jet calculator I am in the right area. Most people I have interacted with on the internet swear by that calculator. I thought that the 45's were the right choice as well. It did have slightly better early response on torque when I had those in. I noticed a decline once I swapped in the 42's.

The rubber are on right, squirrel condoms are good, haven't found any other vacuum leaks. Where is the hidden fuel filter. The only thing that is hidden that resembles a fuel filter is that tip-over valve on the overflow line from the tank.
