I have black soot with my Rinehart .As I recall this is from running rich .How do I adjust to make things a bit leaner ?
Look in tps/rpm and see what the target is around 14. Tps at the rpm you cruise. Point and click on the afr block and hit space bar to get detailed info.^ My mileage is horrible. 27-29 MPG. How do you change AFR's manually and what is a good target to have for a good balance of fuel economy?
