hatchsub Posted April 19, 2006 Share Posted April 19, 2006 Hey all. Its been awhile since ive had a question but this on is stumping me. Im not getting the best gas milage i dont think. I havent actually gotten a chance to do it out and give you a good estimate but im at the pump a lot more now than i was last year. I swapped the intake and carb from the carter-weber one barrel to a hitachi 2 barrel and it runs great except for the milage. I pulled one of the plugs to see if it was running rich and the plug was brown just like it should be. The fuel filters are both about 6 or 7 months old and the carb has about 6 thousand miles on it now. Anyone got any ideas or should i write back when i get exact numbers for gas milage. Last summer it was getting 27mpg on the highway with a 3 speed auto and going along at 4 grand for a long time. Thanks for any suggestions guys. PS this is on an 83 subaru GL four door with an auto 2WD. Quote Link to comment Share on other sites More sharing options...
