If the engine is running = rough due to a clogged injector as is often the = case with new installations, richening the mixture = will cause the engine to quit. This is due to too rich a mixture to the remaining cylinders. Sometimes = leaning is the better course of action. The injector = body meters fuel to the cylinders based on air = demand by the cylinders. The flow divider carefully meters an equal amount of fuel to each cylinder. A clogged injector forces the flow divider to meter an equal but excessive amount of fuel to the remaining cylinders sometimes causing a total engine stoppage. = Jim Frantz >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> LML website: http://members.olsusa.com/mkaye/maillist.html LML Builders' Bookstore: http://www.buildersbooks.com/lancair Please remember that purchases from the Builders' Bookstore assist with the management of the LML.
