Hello gone2fly Welcome, To answer your question It looks like you have it running now. What did you do to fix the problem? You need to read the thread, the answers are there, You would do well to read Forrest Eckstein’s excellent tread as well, Here, http://www.pulse-jets.com/phpbb3/viewtopic.php?f=...

CONGRATULATIONS , WELL DONE , :D That hedge sure took a bashing , good to see that , IMHO the engine quit due to a lack of fuel , one of the problems with liquid propane , is the refrigerant effect, the change from liquid state to vapor state causes a huge temperature drop , and you state that it to...

Looking Good Francisco, (as allways) nice work ,
I experimented with different fuel nozzle designs , and found it difficult to better the Dynajet style , but I dont have a lathe and I am sure there are other styles that may be much better , please do post some updates , good to see you back here

Hi Z, Thanks for posting the vid , I agree the engine almost reached resonant running at the point where it blew the rag out of the intake , There is no question about it, the engine will sustain with both inlets open IF; a, the engine is "in spec" b, there is enough fuel c, you keep the starting ai...

I Agree with what Anders says, re vapor coil length , you are probably short , do consider some external heating ,

wrt running on vapor , you are way short on cylinder size , if you cant get a larger cylinder or paralell up multiple smaller cylinders you wont get that engine to start on vapor

Hi James , Sorry for not replying , been busy , I too worry about the garden hose , that stuff is not suitable , its not fuel proof , and please do try to find a small can , about the size of a soda can would be good 250cc or so, and they are best not sealed , apart from the fact that you need to al...

Hi Zohrke, welcome back , I have not run my engine on Liquid propane yet so I cant really comment on the injector sizing , but ; The coil looks good , that zone gets plenty hot , The injector placement at about 50 mm in from the flare sounds about right , Personally I would consider crimping the cen...

at about 0:20 I think its a crecent wrench comes out from under the car ,

Hi James , The venturi looks good , I am not too sure about the tube sticking in the side, I tried various versions of this, IT SEEMS A GOOD IDEA , but I couldnt get it to work well , heres a pic of how I set the fuel metering device in the venturi , ie axially down the centre line , you asked about...

Man thats amazing , really cool , one thing , that engine sounds like its running at about 1/3 throttle, will it run higher ? if not needs a bigger injector , I do understand that you dont want to wreck your blower , but its in my destructive nature to take things to their limit and beyond , just ca...

Hi James , the ventri looks good , have attached a couple of photos an a pdf , this should give you an idea , very crude , but works , the flow control is something you will have to find , there are many different types , pretty well any of them should work, you just need some way of adjusting the m...

Butane is not so bad , it gets a bad reputation because the pressure drops to pretty well zero in cold weather and usually comes in very small containers , think disposable , these really are of little use to pulsejets , especially of the size engine you have there , I agree with Simon try a rosscoj...
