On the first flight of my recently acquired IO-360, RV-8, I noticed cyl#4 CHT and EGT readings were 20% higher than the other cylinders. I removed all the injector nozzle's to clean them and found the #4 cyl injector nozzle was missing the little flow restrictor insert?? Is the insert available as a separate part?? I was unable to find a source for this part, had to order a complete injector assy, ACS $113.
