Continued with 100 hour engine maintenance. Removed the 90 degree fitting from the gascolator, cleaned the threads and re-installed with fresh Loctite 567. Removed the gascolator bowl and checked the screen - very clean. Removed the carburetor bowls and checked the floats. In the right carb one float weighed 3 grams and the other weighed 4 grams. Decided to replace both carb floats on the right side. Removed the muffler assembly and applied anti-seize paste on the ball joints. Applied red RTV on some of the spring hooks. Did an engine run and it felt rougher than usual. Right EGT was slow in rising but eventually went up and was higher than the left. Did ignition tests at 4000 RPM and the RPM drop was a little more than before but still within range. Checked the engine isolators and I have the "hard" ones and they don't need to be replaced per Van's Aircraft Notification 17-05-19
