Change the spark plugs and wires. Clean the carburetor (at the very least with some spray carburetor cleaner purchased from your automotive store).
18 mpg <--- lol, no! the Nissan 720 series trucks are very easy on gas... at the worst 23, more like 26 if its running right
Any car or truck 25 years or older is considered a classic. The 720 in mint condition can be worth as much as 3,000 and if there the Nissan ST series 4,000. There great trucks and look nice if you lower them 3" and slap Cadillac rims on them. They will last forever just put good oil in them and good gas once in a while.
94 Buick LeSabre, runs great until I step on gas and then it starts to chug and hesitate
