Powertech Generator --engine not running right.

[Gregory OConnor]

A frenchman with a flamingo posted that the crank case breather on
the powertecs vent too close to the airfilter and the paper element
gets a oily residu which gums up with dust quickly. I plan to take
Randys advice, heed the warning of Petes discovery and vent the
crankcase tube out of the airtight compartment.
