If you’re a hobbyist mechanic like me—someone who likes tinkering with cars under the shade and doesn’t want a ton of hassle—this carburetor’s perfect for you. Installation’s almost too easy; aside from tweaking the idle screw a little, it’s pretty much plug-and-play. Now the truck runs like a champ, feels like a whole new ride. I highly recommend this thing!
