trucking45 Posted November 26, 2011 Share Posted November 26, 2011 Okay i got a weber carb with the main barrel number stamped as 27 and the second one stamped as 26 what would be the best amount of turns for the mixture screw Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted November 26, 2011 Share Posted November 26, 2011 You don't count turns - you adjust till the engine runs correctly - either by ear or with a wide-band O2 sensor. Start it at 3 turns out from seated - then adjust your idle speed and mixture (once warmed up) till they are where you want. Get the idle speed down to about 800 and then adjust the mixture to lean-best idle. That is about 1/4 turn out from where the engine starts to stumble and change pitch when you are screwing the mixture screw in. GD Quote Link to comment Share on other sites More sharing options...

GeneralDisorder Posted November 26, 2011 Share Posted November 26, 2011 alright thanks....any ideas as to way the choke could be sticking to? I would have to see it. Probably the linkage is binding and needs to be adjusted (bent). GD Quote Link to comment Share on other sites More sharing options...

GeneralDisorder Posted November 26, 2011 Share Posted November 26, 2011 Sorry - I meant I would have to see it in person. You should pull the e-clip that connects the choke plate shaft to the linkage and see if it's the linkage or the shaft, or misadjusted plates, etc. GD Quote Link to comment Share on other sites More sharing options...
