s'ko Posted March 22, 2005 Share Posted March 22, 2005 Just got it back from SMOG. good news is I dropped CO from 4.44 to 3.22 i the 15mph and from 3.94 to 3.06 in the 25mph. But I still failed Obviously I am running rich. I adjusted the fuel mixture screw ALL THE WAY IN and it's still rich. questions: 1) shouldn't the engine shut off w/the fuel mixture screw all the way in? 2) what else would cause the carb to run rich. Thanks BW Link to comment Share on other sites More sharing options...
Cougar Posted March 22, 2005 Share Posted March 22, 2005 I assume the air intake system is ok, clean filter. Link to comment Share on other sites More sharing options...
Sweet82 Posted March 22, 2005 Share Posted March 22, 2005 The wrong fuel pump control unit box will tell your carb & pump the wrong things I had the wrong FPCU on my buggy for a while. It ran... but it ran rich. Just a thought... Glenn 82 SubaruHummer 01 Forester Link to comment Share on other sites More sharing options...
s'ko Posted March 22, 2005 Author Share Posted March 22, 2005 where is the fuel pump control unit. I did have to swap out my fuel pump b/c I died on me. Another problem that my be related is that both of the duty solenoids are constantly on. I have yet to find someone that can tell me info about the duty solenoids and how they work. (will check the air filter today after work) BW Link to comment Share on other sites More sharing options...
Sweet82 Posted March 22, 2005 Share Posted March 22, 2005 S'ko, Mine was bolted to the same bolt that the hood release latch is attacted with. Should be a black or blue box 2" X 3" X 1". I had a big Mitsibishi logo on mine. Has a six prong wire clip attached to it. Glenn 82 SubaruHummer 01 Forester Link to comment Share on other sites More sharing options...
