(Simrit Radial Shaft Seal Catalogue)

The data presented here is to provide a guideline for selection of a standard seal for a general-purpose application.  The user needs to be aware that many seal design configurations exist to meet specific requirements.  Deviation from the standard limitations provided here should be considered as an indication to explore the possibility of using alternative designs.  This site has sections on the Seal Selection Process, Seal Nomenclature, Dimensioning a Seal, Seal Installation Procedures, Installation Training, Fluid Compatibility, Seal Theory, Surface Condition, Shaft / Housing / Bore Recommendations, Operating Conditions, Failure Analysis, Images of Failures, and Material Properties.  Simrit has put an incredible amount of information into this website.  Well worth looking at.

(Madsen’s Shop & Supply Inc.)

Carburetor adjustment is critical on chain saws and other two-cycle engines.  An adjustment that is too rich will cause a saw to smoke, have insufficient power, and may damage the engine.  An adjustment that is too lean will also produce insufficient power and is more likely to damage the engine.  Proper carburetor adjustment will allow the saw to produce maximum power, produce minimal smoke, run and idle smoothly, and give trouble free service.  This site tells you how to tune a carburetor complete with sound files.
