dave+Sub=trouble Posted June 13, 2004 Share Posted June 13, 2004 I have a 1984 Sub 4x4 and she is running rich. Getting about 14 MPG. I shoot out black smoke when I mash on the gas going up hill... Apart from replacing the O2 sensor and or Coolant temp sensor is there a way to adjust the fuel mixture so that my car will get the right mixture? Got a Hitachi Carb setup.

GLCraig Posted June 13, 2004 Share Posted June 13, 2004 Well for starters, if you have a 84 4x4 you don't have an O2 sensor or any computer control unless it's got Cal emmisions. If you do have Cal. Emmisions then you should check for trouble codes and go from there. If you don't have Cal. emmisions then there is an idle mixture adjustment. Also check your float level. And when did you give it a tune up last Link to comment Share on other sites More sharing options...
dave+Sub=trouble Posted June 13, 2004 Author Share Posted June 13, 2004 Just tuned it up the other day. NGK spark plugs. Perhaps I am due for a carb rebuild.

A weber just opens up the tuning possibilities. Stock hitachis are ok but u cant do much to them in the way of tuning. A weber is a good way of cleaning up the engine bay of a bunch of useless crap and being able to tune the car. Link to comment Share on other sites More sharing options...
