doodlebug minibike

Hello, I'm new here been looking for a doodlebug frame and forks or possibly a roller not sure which is the best version just know I want one. :scooter:

I was recently riding my doodlebug when it shut off. I tried to restart it and it would restart, but the engine lacked lots of power and sounded irregular and would shut off a lot. I let it cool down and cleaned out the carb, changed the oil, played with the mixture screw, cleaned out gas tank...
