The PetrolScooter Pull Start and Flywheel assembly (MPN 26228) is an essential maintenance component designed for owners of 49cc 2-stroke mini moto pocket bikes and dirtbikes. This replacement kit restores the starting mechanism and ignition timing efficiency of your engine, making it ideal for those performing DIY engine repairs. While it offers a precise fit for compatible 49cc models, users must be diligent about measuring their existing assembly against the provided specifications, as small variations in engine manufacture can affect compatibility.

It is designed for standard 49cc 2-stroke engines. Please compare the 98.74 mm diameter and 43 mm height against your current part, as some engine variants may differ.
Yes, a flywheel puller tool is highly recommended to prevent damaging the crankshaft when removing the old flywheel.
The flywheel is constructed from durable alloys designed to handle the centrifugal force of 2-stroke high-RPM operations.
This kit includes the integrated assembly. While parts are often separate, replacing the assembly together is often more efficient for maintenance.
If the dimensions do not align, do not attempt to force the installation, as it will likely result in timing issues or damage to the engine shroud.
Check the gap between the ignition coil and the flywheel magnet; it should be roughly the thickness of a business card.
Ensure the woodruff key is correctly positioned in the keyway and that the center crankshaft nut is tightened properly.
Check the internal recoil spring for proper tension or signs of breakage; avoid forcing the handle if resistance is felt.
To install, first remove the outer engine shroud to expose the existing pull-start and flywheel. Use a flywheel puller tool to safely remove the old unit without damaging the crankshaft threads. Before installing the new assembly, verify that the flywheel matches the 98.74 mm diameter of your original part. When securing the flywheel, ensure the woodruff key is properly seated in the crankshaft slot. Over-tightening the center nut can damage the unit, so follow standard torque specifications for 49cc engines. Regularly inspect the pull-start cord for fraying and keep the area free of excess grease to prolong the life of the internal recoil components.
