If your 2-stroke engine runs better with the choke on, it suggests an issue with the fuel-air mixture. The engine may be running lean, meaning it's not getting enough fuel. Check for clogged jets or fuel lines, which restrict fuel flow. Additionally, inspect the air filter for blockages. Cleaning or replacing these components can resolve the issue. Running the choke enriches the mix, temporarily compensating for fuel delivery problems.
