Here are a couple of pics and videos of short runs it's done so far. I still need to do some fine tuning, and hopefully it'll be a good runner. I think I bit off more than I could chew with this one!
Maybe it's the angle of the shots but it looks to me like your flame may be a little too high and your perhaps not getting the necessary heat transfer. ??? :-\
You could be right. I made the burner to get the flame into the position that Jan Ridders suggested, but I may take a skim off the burner body so I can adjust it down or up with packing if required. I think it might be sucking in a colder part of the flame. I have a few things to try so watch this space!
Congratulations, Nick. If you can get a flame licker to run, you can get anything to run! Sometimes success with these finicky engines is more rewarding than the ones that work right out of the chute!
Rick, I've seen videos of your poppin engine which is fantastic so I'm sure if you wanted to you could easily make a working version of this one now. These flame lickers are tempremental to say the least though! Kinda glad it's finished in a way but very satisfying to watch! I think an i.c. engine will be my next project, so I'll probably have to go through all this again and worse!
