I'm an experienced shadetree mechanic, but I mostly do European stuff so I'm in unfamiliar territory here. Friend of mine has a 1989 Accord LX, it has the carbureted engine with a rats nest of vacuum lines, valves, solenoids, and other junk that ends up making it so much more complicated than fuel injection would have been. Anyway the car is getting around 22 mpg on the highway which strikes me as very low, even for having an automatic transmission. A mechanic looked at it once and said he thought the choke wasn't opening fully, but without taking some things apart I can't even see what actuates the choke, is it vacuum? If there's something fairly simple I can do to improve the fuel economy I will, but this thing looks like a nightmare to work on compared to what I'm used to and I don't have a ton of free time so I don't want to dig in too deep.
The other more minor thing is the trunk light doesn't work. Bulb is good, I popped the light assembly out and measured no voltage on the wires to it. Looking around, I don't see a pin switch anywhere that would turn it on when the trunk is opened, and turning on the dome light in the passenger compartment didn't change things either. Where does this light receive power from and what turns it on?
