Features, Architecture & Package Contents

Horizontal Single-cylinder Four-stroke Mini Gas Tractor Engine ICE Model 1.9CC M21

Features:


.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.
.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.
.Each part of the engine was carefully designed, processed as well as made of brass and stainless steel, working in conjunction with a wooden base for easy display&control and stable operation.
.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.
.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.
.Notes: 1. If the engine is failure to start normally under the normal ignition and cylinder compression, it is likely that the carburetor needle will need to be adjusted.
2. After tightening the main oil needle on the carburetor, loosen 1/4 turn and start the flywheel to make the mixture ratio of gasoline and air reach the normal working mixture ratio after several times.
3. Turn off the power switch when the machine stops.
.Starting Steps: 1. Check the engine and wire from the board to connect the tank line, then install 3 AA batteries (4.5V).
2. Add gasoline (95#) to the tank. After filling, turn the flywheel on the right side of the engine, which allows the mixed fuel to enter the cylinder to ensure that there are no empty tubes inside.
3. Turn on the power and quickly turn the flywheel on the right side to start the engine.
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!
