Hi Giorgio. You may have already seen these videos. Jay Leno is an American comedian and actor who collects old stuff and has a museum. Steam cars, stationary engines. If you haven’t seen these videos you will enjoy them.

Giorgio, I think this man uses a Deutz engine, the Yugoslav Aran-Torpedo is manufactured under this license, otherwise it is an Aran diesel but it would be very easy to convert it to spark ignition, it is an indestructible machine, …
Very nice video , thanks for posting 
some days ago i have seen such a motor in a internet market in germany,4 hp, gasoline, only for 300 euro…85 kg, horseshoe magneto ignition…
also deutz factory…
for me to far away to reach, maybee with chargas the 4 hp would be in reality 3 hp or less…??
Giorgio, these older gasoline engines have a rather low compression ratio, so the power is also low, especially on wood gas. Probably the 4 hp engine is much smaller than the one in the video, the Aran engine weighs approx. 300-400 kg and has a working volume of 1100 cc, the power is approx. 10 hp. It is likely that this engine in the video is of similar size and similar power. I intend to attach strong magnets to the flywheel and use an ignition coil from a chainsaw for ignition,…
Sounds like a home brew crank trigger ignition Tone. Why am I not surprised that you would make one? I just shake my head in wonder reading your posts.

thanks wayne, and also chris for having opened this interesting forum…!!!
otherwise we probably never have had meet us…always a lot of inspiration and experience from the members here…
Mr. Tom, I think we are very kindred spirits (like most here), but every person is unique. Modern people are oriented in such a way that they run to the store to buy everything, old things are hardly repaired anymore, but for me the greatest satisfaction is if I manage to do something at home. This tractor was practically used up and suitable for scrap, I bought some new parts for approx. 500 Euros, but everything else is made from scrap material, now it has “priceless” value for me, it really is a universal machine.
Mr. Bob, when you mention the picture showing how the smoke rises from the gasifier, let me say that this is how I “heat” the gasifier lately, I open the non-return valve below (put a twig under the flap) and open the lid, this is how a natural draft is created, the embers below it heats up, and a lot of steam is released at the top, then it only takes a minute or two to blow the fuel with a blower and get the gas to work.
I thought I was the only one that did that. I have to be careful because the tar will catch on fire and really get a fire going out the hopper top. It does help the upper part of the hopper clean the tar out of the gutters and drain to the condensation tar/water tank in colder weather conditions like now we are having.
I used an online translator for the pdf file. It didn’t translate everything but got the main description.
