<br><font size=2 face="sans-serif">I installed one headshim in the two Webra 160 (Aggressor and Lazulite). I did not notice any difference in running, nor a compression reduction. </font>
<br>
<br><font size=2 face="sans-serif">Also, I've gotten mine to be meticulously clean while running. After a day's flying, there is almost no need to clean the plane. Simple, but with some routine checks here are the steps:</font>
<br><font size=2 face="sans-serif">1. Use RTV between the header and engine (check or redue once a month if residue develops on plane)</font>
<br><font size=2 face="sans-serif">2. Ensure all bolts are tight (no lie) (engine will still run with loose headbolt)</font>
<br><font size=2 face="sans-serif">3. Header & Pipe coupler: I found zip ties to not adequately seal the silicone coupler. For instance, if you examine the plane and there is exhuast residue on the plane before the stinger, then you have a leak somewhere. After installing small hose clamps, and checking every so often, there is no "exhaust" residue before the actual exhaust stinger.</font>
<br><font size=2 face="sans-serif">4. Pinch or disconnect fuel line: If you pinch the fuel line in between flights, or just plug the line, there will be little to few fuel drops exiting the carburetor while the plane is sitting. </font>
<br><font size=2 face="sans-serif">5. Run exhaust stinger extension:</font>
