by Gosh, that's definitely a splendid run!! Dear bladerizer, could you please provide me with any clues/refs on WHAT I shoul do to make my little culprit run the same way. Mine runs max 10-15sec unlike yours somewhat HARD & NOISY and surely needs proper adjustment if not complete overhaul. thank you

@dp7090

Thanks for the nice words. If you have the same engine, then try this. It seems like your engine is going at full revs. This will break the engine - mine got it's piston crushed that way.

Unscrew the cylinder lock ring and then turn the whole cylinder counterclockwise. This will raise the cylinder, therefore letting less gas in, therefore letting the engine run slower and for longer. After setting the cylinder to a wished height, be sure to tighten the cylinder lock ring.

how long does it run for on a full tank

[bladerizer]

Haven't tested it yet. In such a setting as in the video, I believe about 10 mins? It depends on the timing. Minimum running time for a full tank is specified at 15 seconds in the manual.

the tank is then ice cold o: look at the tank !!

@ the first three commentors: co2 is under pressure in these little bottles, and as the engine uses it up, the pressure in the canister drops, decreasing the temperature of it. so as it runs the temperature drops still, and water in the air condenses on it freezing.

where did you get the propeller

The CO2 evaporates not condensates ,maxotromeros !

check out the ice that's building up as the co2 condensates.
