VORTRIXE & OKMO M21 Internal Combustion Single-cylinder Four-stroke Gasoline Engine
M21 Gasoline Engine for Tractor:
- Based on the diesel engine of a farm tractor from the last century, the miniature gasoline engine model embodies the spirit of different ages in a wonderful way.
Retro Design:
- Designed with classic body lines, the retro machine restores a host of authentic engine details, including a new carburetor, lift throttle, and floater-controlled valve with gasoline.
Brass and Metal Made:
- Each part of the engine was carefully designed, processed, and made of brass and stainless steel, working in conjunction with a wooden base for easy display & control and stable operation.
RTR Version:
- Built with start and ignition equipment, the engine is ready to run and friendly to novice model enthusiasts. When running, you will satisfy and marvel at its operation.
Collection or Gift Choice:
- As a coveted collection, the engine model is worth showing and playing, suitable for personal use and a high-end gift to friends and families at major festivals.
Warm Tips:
1. If the engine fails to start normally under standard ignition and cylinder compression, it is likely that the carburetor needle will need adjustment.
2. After tightening the main oil needle on the carburetor, loosen 1/4 turn and start the flywheel to allow the fuel-air mixture to reach the normal working ratio after several attempts.
3. Turn off the power switch when the machine stops.
How to Start This IC Engine:
Step 1. Check the engine and wire connections from the board to the tank line, then install 3 AA batteries (4.5V).
Step 2. Add gasoline (95#) to the tank. After filling, turn the flywheel on the right side of the engine to allow the mixed fuel to enter the cylinder and ensure there are no empty tubes inside.
Step 3. Turn on the power and quickly turn the flywheel on the right side to start the engine.
Step 4. During startup, gently cover the inlet with your hand and release it instantly a few times to allow the machine to suck in fuel smoothly. This step is not required after a normal startup.
