Hi
I am new here.
I have an ER100? from Hubert. I have not been able to get it to start.
I have been following all of the recommendations in the paperwork that came with the PJ.
I am using a fuel pump from a 160 class turbine powered thru a speed control running off of a 6 cell NiMh pack.
I have a spark generator going to the stock spark plug on the top of the PJ.
I tried an electric leaf blower and had little activity at all, It may just have not been big enough.
Best so far was using an air compressor at 120psi with a blow gun.
All of the fuels I have tried have 5% oil added for the pump.
With each fuel I have I have started with the pump at a very low speed and worked my way up very slowly until it was obvious that I was putting in way to much fuel.
I first tried it with straight Kero
Then tried 40/60 Gasoline/Kero, then 50/50 and 60/40.
With all fuels all I get a large individual pops and lots of flames.
One I stop adding fuel I can get it to run a short bit (about 1 second) while it burns off the puddles in the combustion chamber.
I have no clue as to how much fuel I should be putting in to run so I keep trying all settings from way to little to way to much and everything between.
The next thing I was going to try was mixing propane with the compressor air to see if that can get some fire before adding in the Kero. But again I have no idea how much propane flow is needed. I would hate to have to much and then have it find the spark.
I am also unable to find any info on how I should be adding the propane, Mixing it with the compressor air, separate propane line and just blow in plain air.
I have watched every vid I can find on You tube but there is always just a brief glimpse of the starting equipment from to far away to see how it is built. Some use propane some just start using the onboard fuel.

286 views so far and no Ideas as to what I am doing wrong?
I see lots of vids of these flying so I am sure it is something I am not doing right.

Re: Starting a Valved Pulse Jet
Do you have a video of your setup and starting attempt? That could be very useful in identifying your problem. Have you considered it might be the engine that's problematic and not your fueling arrangement? some pictures of your engine could be useful. Any leaky welds, bent valves, dents? etc.
Quantify the world.
Re: Starting a Valved Pulse Jet
I am working on trying to get a video and pics.
I have to put the test bed back together as I scavenged some parts for another project.
Here are a couple of file pics that show the PJ.
