Nothing yet. I have done a lot of much needed maintenance such as hose and belt changes, tune up, fluid changes.
If you're looking for an off-road vehicle that you can use on road, this is it. Plenty of room, decent on road ride, very poor gas mileage, but hey, it's a Land Cruiser. Reliability when you are miles away from anything is what counts most.
What's your gas mileage? I can't get more than 10mpg out of mine... driving granny style.
Properly tuned you should only get about 12-15MPG. Maybe a little more if you really tweaked it. If you have larger tires than stock make sure you account for that in your mileage calculations. If you have 31" or 32" tires then ad about 10% to your speedometerreading and the same for the odometer.
Make sure your timing is correct, good basic tune-up, and if your carb is really old, clean it out or rebuild it.
