 I'm pretty sure the fuel distr= ibutor ("spider") on the Continental system is the same as on the Lycomings= and if so, it is what controls fuel distribution at idle.  There is a= narrow slot for each injector that is progressively uncovered as the flow = increases, so if one slot becomes partially plugged it will affect the idle= flow.  Once the flow increases to "flight" values the plunger pulls a= ll the way out of the bore and from than on flow balance is determined by t= he injectors.  Bottom line is that I don't think that symptom is relat= ed to anything else, and if the engine runs okay at idle it usually somethi= ng with which not to be concerned.  Just my opinion.

From: Dico Reijers:=
I've just noticed that the #4 CHT /EGT is very low compared the t= he rest =3D
(see graphs taken at 1040 RPM idle).  If I push the pow= er to 1600RPM or bet=3D
ter, the CHT/EGT for #4 come up in line with the= others.
