What is the best used engine for shifter kart?

Hey there, looking to build a shifter kart but I am a bit of a novice. What would you recommend as the best cheap used engine for a shifter kart. Thanks

Welcome. Get a 250cc bike engine. That will do it

The Honda CR-80 or CR125 are the most commonly used engines on shifter racekarts, so new (and used...) parts you'll need like a motormount, chamber and shifter J-arm are easiest to find
