CISON FL4-175 Installation Tutorial

Features:

Exquisite mini shape:
FL4-175 engine has a unique compact appearance, simple but reliable structure, small size but large displacement. A collision of retro classics with modern machinery, it will work impressively.

Long stroke, high torque:
The side valve structure is adopted, the center of gravity is lower, and the weight is lighter. Taking the long stroke as the design basis, it effectively provides higher torque output.

Responsive and powerful:
Metal stainless steel one-piece printed intake and exhaust pipes, independent single carburetor design, easy to adjust, more sensitive throttle response, and low and powerful sound.

Effective and long-lasting work:
The external oil pump is used to supply oil to the crankshaft splash, and the independent lubrication effect is better. It is recommended to use a micro oil filter element. With water circulation cooling, the engine runs longer and has a longer service life.

Well-made:
The main body of the engine is mainly made of aluminum CNC precision machining, the special bimetallic cast iron piston ring, the high-precision hardened cylinder liner, the one-piece hardened crankshaft, the surface sandblasted and oxidized, rich in metal texture and mechanical sense.

Convenient ignition:
The self-developed four-cylinder electronic igniter is small in size and strong in anti-interference, which makes the ignition operation of the engine more stable, and is more friendly to players who use remote control electronic equipment.

Upgradability:
The oil pan has a reserved observation window, and the transparent window can be modified to observe the operation of the crankshaft in real time. The flywheel side reserves the installation position of the simulated automobile mechanical manual clutch for later players to upgrade.

RC Compatibility:
Lightweight structural design, better compatible with RC models. It is the perfect "heart" for low torque demanding 1/8 and 1/10 scale model climbing bikes.

Collection gift:
It is a perfect addition for mechanical enthusiasts, engine model enthusiasts and collectors, and it is also a good choice for RC oil-powered models. It can be used as a high-end personalized gift for family and friends.

Warm reminder:
The engine does not include the base, CDI igniter, spark plug, oil filter, etc. Please use the machine according to the instructions in the manual, so as not to damage the machine due to bad operation. If you have any questions, please contact us in time.

Really nice but with some birth defects

Aesthetically and technically it is a beautiful engine. Unfortunately I encountered several difficulties during the functional tests. First the starter gears were not to proper tolerance and did not slide. Being able to adjust the ignition timing is really difficult. The spark plugs almost all broke because they were defective (Enginediy supplied me with 4 new ones under warranty). However, I've never heard the engine running on petrol, it never started well. I converted the ignition to glow and methanol to 25% nitromethane and now the engine runs really well. However, I had to review the tolerances of the water pump turbine, as it got stuck rubbing on the bottom of its seat. The last problem I encountered was an inaccurate flatness of the crankcase which prevented the correct tightening of the head, causing the gasket to break several times during operation. I also solved this problem by retouching the top (Lucas promised to send me some new gaskets). Now the engine runs very well, has a perfect idle and has a lot of anger. I also ordered the intake manifold they supply as an upgrade, improving the running.
