here is the video again, the old link of which no longer worked is obsolete.

The typical non-glowing flame of the methanol fuel is unfortunately hardly visible due to the glaring sunlight. At the end you can see them briefly.

You can see other effects quite well, such as the rocking fuel tube, which comes from the deformation of the very hot evaporator tube. on the left you can occasionally see the supersonic fuel vapor "blasting" into the engine.

hints:

the unsteady combustion comes from the lack of pump pressure, formerly a bigger pump was applied, but I haven't already as powerful pump.

note : methanol vapor saturation pressure at 250 degC is about 100 bar !! And my little toy-pump in this video achieves just 8 - 12 bar.
