Help please

My doodlebug has a 79cc predator that stalls when you let off the throttle. It starts and warms up fine. Runs good till you slow down. Starts right back up after stalling. Any help would be appreciated.

The 79cc engine that comes with the DB30 is VERY temperamental. The carb comes from the factory lean for EPA reasons and is non adjustable. Most people do a engine swap and I would recommend that option. I putt a Honda GX120 on my wife's. The predator engine are good a option. Otherwise look here for 79cc options. https://affordablegokarts.com/collections/79cc-performance-parts

DBs came with a 97cc flathead engine, quite different than a 79cc OHV Predator.

The solution may be as simple as adjusting the idle speed...
