My 86 R80RT fuel consumption has dropped from 47/48mpg to 38/39 within 3000 miles.
Replaced the old crackomatic ign coil for the late type together with the matching ign controler. This cured poor starting and some vibration but had no effect on fuel consumption. Then changed diaphrams, checked float levels, dropped needles one notch to second from top and checked valve clearances. Small improvement to 40/41mpg. Performance and general carburation both excellent. Total mileage 38,000
Any ideas?? What is normal average consumption.
