Hi John, is it possible that your fuel system is constantly feeding some fuel to your Weber?

That may explain why you have to lean the fuel injectors to minimum -  also, if you turn both injectors off, the engine should qui= t immediately – if not where is the fuel coming from?=

Subject: [FlyRotary] Mixture Condition

 

I have narrowed the mixture condition down to the fact that when it starts to miss up I can keep it running poorly by turning the mixture control down to minimum, but if I turn off the primary injectors switch the engine app= ears to run okay, the secondary injector switch doesn't seem to make any difference in the way it runs at 4000 rpm or idle.  The injector switc= hes as well as the wiring harness I purchased from Bob and all wires are solder= ed and covered with heat shrink.  I checked the best I can with a light a= nd mirror and everything looks okey under the panel.  It runs the same, rather in mode A or B.  On rereading the instructions I see that the c= oil disable can only be checked in mode B, so I haven't done that yet. 

I turned of the fuel pump and with the injector switch's off the engine conti= nued to run until the fuel press was down to 17 pds. and quit.  I turned on= the fuel pump (LP) to the Weber and it started immediatly.  This condition started at 7.2 on the hour meter.  I really now don't have any idea wh= ere to start looking for the problem.  JohnD
