Thank you for choosing the CISON V8 Full Set from Stirlingkit!
This guide shows you how to mount your CISON V8 engine on the metal base (display stand) and connect the starter kit: the radiator, fuel tank, coolant reservoir and electrics. The best way to learn it is to watch it done, so we've put the full video right here, followed by the key points to keep in mind.
Why it's worth watching: the CISON manual covers building the engine itself, and this video picks up where it ends, showing how everything comes together on the base. It's simple once you've seen it.
Watch: mounting the CISON V8 on the base and connecting the starter kit
The video starts at the base and starter kit connections (5:03). Scroll back to the start to see the engine build too.

Key points while you watch
- Fit everything loosely first, check hoses and wires reach without stretching, then tighten.
- Fuel: fuel tank → carburetor, using Tygon-type tubing. Keep the tank vent open.
- Cooling: radiator ↔ engine, plus the coolant reservoir. Check every joint for drips.
- Electrics: 12V supply (at least 15A) → CDI and switch → starter.
Where everything goes on the CISON V8 base
Build the engine first, following the manual. Then place everything on the base:
- Engine in the centre, on its mounting brackets
- Radiator behind the engine
- Fuel tank and coolant reservoir side by side on their brackets, at the front of the base
- CDI, switch and start button on the base, within easy reach
Fit everything loosely first, check the hoses and wires can reach without stretching, then tighten.
Connect the fuel, cooling and electrics
1Fuel: fuel tank to carburetor
- Run a fuel line from the tank you've chosen as the fuel tank to the carburetor fuel inlet.
- Use Tygon-type tubing. The manual (p. 46) advises against silicone for fuel, as it isn't suited to gasoline. Needle-nose pliers make it easy to push the tube onto the inlet.
- Route the line clear of the exhaust and anything that moves.
- Keep the tank vent open. A sealed tank builds pressure as it warms and can leak (manual p. 45).
- Fill with pure gasoline, 92/95 octane. No oil goes in the fuel.
2Cooling: radiator, engine and coolant reservoir
- Connect the radiator to the engine's water connections, as shown on manual p. 45.
- Connect the other tank, the coolant reservoir, to the water pump side of the engine, as shown in the close-up clip.
- Push each hose fully onto its fitting and check none are kinked.
- Fill with coolant (ideally one with added lubricant, manual p. 6), then look over every joint for drips before you run the engine.
3Electrics: 12V, CDI, switch and starter
- Use a 12V supply that can deliver at least 15A (manual p. 6).
- Connect the 12V supply to the CDI and to the switch, then the switch to the starter, following the wiring diagram above.
- Connect the CDI to the distributor and the Hall sensor wire, as shown on manual p. 45.
- Keep red to positive and black to negative throughout.
Before the first start
- Check for a spark: switch the CDI on and turn the flywheel (manual p. 46).
- Prime the oil pump and fill the oil pan with 25ml of 4T 10W-50. See our oil pump priming guide.
- Set the carburetor to the factory settings: main needle 2.0 turns, auxiliary needle 0.5 turns (manual p. 46). See our carburetor tuning guide.
- Check every fuel and coolant joint one more time for drips.

Common questions
What does the CISON V8 Full Set include?
The Full Set is the CISON V8 engine plus the metal base and the starter kit, which brings the radiator, fuel tank, coolant reservoir and starting parts together on one display base. Spark plugs are included with the Full Set.
What power supply does the CISON V8 Full Set need?
A 12V supply that can deliver at least 15A (manual p. 6). The CDI and the starter both run from it.
Can I use silicone tubing for the CISON V8 fuel line?
No. The manual (p. 46) recommends Tygon-type tubing for fuel, because silicone isn't suited to gasoline. Silicone tube is fine for the oil and coolant lines.
Why does the CISON V8 tank need its vent open?
As the engine warms up, pressure builds inside a sealed tank and can force fuel or coolant out at the joints. Keeping the vent open lets it breathe (manual p. 45).
Which CISON V8 tank is the fuel tank and which is the coolant reservoir?
They're identical, so either can be used for either job. Pick one for fuel and one for coolant, and label them so they don't get mixed up. Never put fuel in the cooling circuit, or coolant in the fuel line.
Is there a video of the CISON V8 Full Set being connected?
Yes. Watch the CISON V8 assembly video from 5:03, JohnnyQ90's build video from 1:55, and this short clip for a close look at the fuel and coolant lines.
