R29 4.2CC Miniature V-Twin Engine Motor OHV for Mini Chopper Bike Motorcycle
Features:
.Based on the V-twin double-cylinder Knucklehead motorcycle engine in the 1970s, the miniature gasoline mini knuckle head engine model embodies the spirit of different ages in a wonderful way.
.Designed with classic body lines and cold-cooling structure, the retro machine restores a host of authentic engine details, including a new carburetor and lift throttle.
.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.
