Is my 340 Overcarbed? Avg 5-6 MPG
1....Sounds to me your speedo is AFU. I've bought at least 3 "used" GPS off CL and thrift stores from 17--40 bucks. These make GREAT speedos and odometers (they have a trip odo) So that's one thing.......getting accurate measurements
2....Fill up at the same station if possible, with the car in the same pump IE to keep the tank "level" as some pumps are slanted left / right / front / rear
3....Way too fat at cruise
4....You need work on the ignition curve. You probably want a shorter curve, and you NEED to get something with a vacuum advance.
5....That combo is NEVER gonna do that great with mileage. If you want mileage, pull that cam.
This is one of my cheap used Garmin "Nuvi". I've been a bad boy, LOL
