webra 160 - meticulously clean

[Jim_Woodward at beaerospace.com]

I installed one headshim in the two Webra 160 (Aggressor and Lazulite).  I 
did not notice any difference in running, nor a compression reduction. 

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:
1.  Use RTV between the header and engine (check or redue once a month if 
residue develops on plane)
2.  Ensure all bolts are tight (no lie) (engine will still run with loose 
headbolt)
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.
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. 
5.  Run exhaust stinger extension:

Thanks,
Jim W.

Motor does not come with head shim. Got 3 motors that way. I haven't had a 

need to use them either.
