  • I've just found this brilliant video! I see your piston actually protrudes slightly past the left hand edge of the port. Mine doesn't quite get there so the port doesn't fully open. Do you think this could stop it running? It still opens enough to draw in the flame, I'm at a loss with this engine! The only thing I can think is that my piston and valve aren't a good enough fit but they seem ok when testing. Many thanks, Nick

  • I've just found this video and can see that your piston pushes the valve further open than mine. Your piston actually goes slightly past the left edge of the port where as mine doesn't quite reach it - that was a slight mistake on my part, do you think that could be stopping it running? The port still opens enough to draw the gas in! Many thanks.
