I have a 1985 dodge ram d150. It has a 318 with a factory Holley 2 barrel carb on it. One problem is that it smells like it is burning a lot of gas, or running rich. It also only gets like 7 miles per gallon. It does have the A999 3 speed automatic transmission, but it should do better than that. Another problem is that it doesn’t have much power. It only has 83,000 miles on it, but you can put it to the floor and it speeds up, but not that fast. It doesn’t downshift into 2nd gear unless you’re going 35 miles per hour or slower. I was wondering how to fix these problems, and if it is the carburetor. Thanks.
