3.2cc Mini Flat-twin Motorcycle Engine Model  4 Stroke Gas Interal Combustion Engine Model R69

Features:


.Motorcycle Engine: A flat-twin engine is a two-cylinder internal combustion engine with cylinders on opposite sides of the crankshaft. The most common type of flat-twin engine is the boxer-twin engine, where both pistons move inwards and outwards at the same time. The horizontal cylinder block allows the cylinder to avoid obstacles on the front wheels of the motorcycle and obtain excellent air cooling performance. Two symmetrical exhaust pipes are one of the hallmarks of a horizontally opposed engine. Featuring the advantage that lies in its ingenious structural design, every component of the model restores the mechanical principle to make this all-metal engine model start and operate.
.Sophisticated Manufacture: Treated with precision casting on the entire engine and carefully-crafted parts, the contour of the cylinder and other parts with casting process are very round. The engine model boasts the most significant feature of motorcycles in that era. providing you with the unique charm brought by the mechanical operation of the engine.
.Steps to start the engine:

(1) Check the engine wiring from the wooden base, connect the fuel tank oil pipe, and install 3 AA batteries (4.5V);

(2) Fill the fuel tank with 95# gasoline. The flywheel rotates clockwise multiple times on the right side of the engine (the surface of the power switch). This will make the mixed fuel completely enter the cylinder and ensure that there is no air in the fuel pipe;

(3) Turn on the power switch and then quickly turn the flywheel clockwise. Start the engine on the right side (surface of the power switch).
.Notes:

(1) If the machine cannot start normally with normal ignition and cylinder compression, it is likely to need to adjust the carburetor oil needle;

(2) After tightening the main oil needle on the carburetor, loosen 1 /4 circle and start the flywheel to make the mixing ratio of gasoline and air reach the normal working mixing ratio;

(3) When the machine stops running, turn off the power switch.
.Superb Model & Gift: This stunning mechanical craft allows you to feel the allure of the engine when working, suitable for personal use and an impressive gift to friends, families and model lovers on major festivals.

Squeaky ball
Color: Large Set of 4
Perfect squeaky ball. Dogs love them. I love that they're durable and their thickness aids their durability. My Great Dane will play alone for hours with a ball.

One Tough Ball!
Color: Blue
Our dogs are loving this ball. Our 1 yr old hound is a world-class chewer and he can't make a dent in this ball. The interactive buzzing and bouncing keeps them entertained for long durations. It's a mite noisy but the barking from the 1 yr old is much louder, lol. Even turned off, they like playing with it and chewing on it. Based on the tough construction, we think it will last much longer than traditional chew balls.

If you love your dog…don’t buy this.
Color: Orange
We have a nonaggressive English cocker. She opened the ball every time she played with it. And yes, we are closing it as hard as we can. I do not recommend this toy for any dog! This is a dangerous toy for a dog that is not supervised.
