You’ve just finished assembling your Cison V8.
Everything looks right.

You’re ready to start it.

:backhand_index_pointing_right: This is the most exciting moment

:backhand_index_pointing_right: And also the moment where small mistakes show up fast

The truth is:

Most “won’t start” or “runs badly” issues
come from things that could have been caught before the first start

:backhand_index_pointing_right: This checklist is based on real build experience
:backhand_index_pointing_right: Follow it once, and you’ll save yourself hours of troubleshooting

1. Cooling System :thermometer:

Recommended:

50/50 mix of distilled water + coolant

Why this matters:

  • Lubricates water pump

  • Prevents corrosion

  • Keeps temperatures stable

Before starting:

  • Cooling system fully filled

  • No visible leaks

  • Water pump spins freely

:warning: Avoid tap water → mineral buildup over time

2. Engine Oil & Lubrication :oil_drum:

Recommended:

10W-30 or 10W-40 engine oil
(non-energy-conserving type preferred)

Check:

  • Oil level is correct

  • Oil lines are secure

  • Crankshaft turns smoothly by hand

:light_bulb: Pro tip:
Add a little oil to key moving parts before first start

3. Ignition System :high_voltage:

This is where many first-start failures happen.

Check:

  • Spark plugs installed (not overtightened)

  • Ignition wires fully seated

  • Correct firing order

  • Battery fully charged

:warning: Low voltage = weak spark
:backhand_index_pointing_right: Very common startup issue

4. Fuel System :fuel_pump:

Recommended:

  • High octane fuel (95/98 RON)

  • Ethanol-free if possible

Check:

  • Fuel lines secure

  • No leaks

  • No kinks

  • Carburetor at baseline setting

:warning: Do NOT aggressively tune mixture on first start

5. Mounting & Safety :toolbox:

Before starting:

  • Engine firmly mounted

  • No tools or loose objects nearby

  • Hands and cables clear of moving parts

:sunglasses: Eye protection strongly recommended

6. First Startup Procedure :rocket:

When starting:

  • Start at low throttle

  • Let engine idle for 1–2 minutes

Watch for:

  • Coolant flow

  • Oil/fuel leaks

  • Unusual noises

:warning: Do NOT rev immediately
:warning: Do NOT hold high idle early

7. Break-In Period :hourglass_not_done:

First 1–2 hours:

  • Low to medium RPM

  • No sudden throttle changes

  • Allow cooling pauses

After first run, re-check:

  • Bolts

  • Belt tension

  • Oil level

  • Coolant level

:heart: Final Thoughts

This is not just a checklist.

:backhand_index_pointing_right: It’s the difference between:

  • A smooth first start

  • And hours of frustration

Most problems people face:

:backhand_index_pointing_right: Are not “engine defects”
:backhand_index_pointing_right: They are missed details

Take your time.
Do it right once.

And when that engine starts
 :fire:

:backhand_index_pointing_right: It’s not just a machine running

:backhand_index_pointing_right: It’s your build coming to life

:rocket: Good luck — and enjoy your first start
