Hi, Kristijan!

To avoid too much suction resistance, it has to be measured for a 500 – 1000cc four cycle motor.
It can be vertically or horizontally sucking. An important point is, that the float chamber has a screwed-on lid, easy to open and close; it will be opend many times during the testings…
Preferably with a turnable throttle flap, as it has to be taken out sooner or later anyway. (Good scrapyard hunting!)
Such wishings should never be worded…

I was thinking to make a system lyke this
1 air intake
2 air valve
3 exhaust valve
4 water carburator
5 gasifier
l think a 50ccm moped carburator shuld do the job as i am only going to put a litle water in the air stream
Hope is makes sence to you the skech is just a fast drawn one 
Thank you for the drawing. Now I can go back and understand what Max is talking about TomC
Hi, Kristijan

Yes, so you have predicted!
On monday the scrapyards will open!

Hi, Tom!

You mean: “Now I can go back and misunderstand Max…”
It’s spelled out in mes. 121.
Max
Max; I hope no misunderstandings because I respect your ingenuity. I do have trouble “visualizing” your “verbal” descriptions. I try to sketch out what I understand you to be saying. Some time back I posted a drawing of what I thought you were telling us would make a good gasifying system for cold weather. I have another laying on the table next to me that says “Charcoal Gasifier Nozzle” per Max. And then there was the one I recently posted that you tell me you had nothing to do with. I would not work at these drawings if I didn’t have respect for the information you try to give us.TomC
I have to say I agree with Tom sometimes it is hard to imagine some things that are verbaly descrybed (l mean in general ) exspecialy for us members that do not speak english as its primary language. You can imagine it is eaven harder to describe things in a languade you just bearly know.
Dito!
Funny, but to me your english, Kristijan, is easier to read then most of the american’s. However I think TomC, Max, Don and Wayne are fairly easy to read as well.
Maybe it has something to with that our school english text books were made when they were 
I had a thought about timing advance on these systems which rely primarily on a cam position sensor. Maybe some of you with more engineering experience could chime in.
It seems to me that it would be relatively easy to build a simple circuit to introduce a delay into the reporting of the cam position.
I am guessing that the cam position sensor is a hall effect sensor, or something like that, which fires when a rotating magnet passes the sensor or something.
If that were the case, then couldn’t you make a simple analog circuit, with a variable capacitor, to introduce a delay in the signal?
For example, if the sensor would normally report 10 degrees before top dead center, introducing the delay would mean that it was now reporting at 5 degrees before top dead center (for example).
Would this work?
What if you wanted it 25 degrees before top dead center? We want it advanced for wood gas, don’t we?
Don, you’re typing faster then I do.
I’ve thought about that too, but i think the computer uses info from several sensors to make decisions and altering just the one may confuse the computer and give unwanted difficulties.
Kyle, maybe if you delay it enough to hit the next stroke. But then it will effect timing when sudden revving up and down.
Hi guys; Sorry I can’t find it right now, but we just finished a discussion on timing on another thread. I was trying to make a case for using the “knock sensor” Anyway if I could find that thread, I believe some where in the discussion it was stated that the Dodge is one of the few engines that really benefit from “mechanical distribute advance”. In most others the computer does a good job of adjusting it. I know I have heard it said that the Dodge V6 does not gain benefit from a mechanical advance ( on the other hand I do it on my V6 and can NOT say definitively if it helps or not ) Then you come to a computer controlled 4 cylinder and I really doubt if a mechanical control will help.TomC
Right Jo, but not just when suddenly revving up or down. A simple time delay for adjusting the retard (from 10 to 5 in the example) is good for only one speed. At double the speed the same delay would effectively cut the retard in half since the engine would rotate twice as far in the same amount of time.
Autch!!! Of course!!! You’re right.
I usally sleep on it - this was just a sudden thought.
Consider my previous post deleted
Yes. Of course you are right. So much for that idea.
Maybe it would be possible to physically change the position of the sensor slightly?
The only other solution I see to “dummy” the sensor would be to interpose a more complex circuit, which varied the delay based on RPM. You could always do it with an Arduino, but that would not exactly be simple, elegant, or cheap.
Hello Mr. Tom
I have run some motors on woodgas that were old enough there were no computers. 84 ford 460 V-8 , 87 dokota 3.9 V-6 and a 4 cylinder tractor . All of these I could retard and advance the time by a little twist of the distributor. In the case with these motors it made little difference in performance and speed and you would really have to listen or feel for it.
With the computerized V-8 dokotas and rams it is like night and day when the time is advanced. ( just ask anyone that has operated one 
) Little power and plenty of backfires if not advanced 
The experts say the timing can not be advanced on these motors. I agree but we can make them cross fire ( jump to the next peg or plug wire )
Below may be the thread you were looking for. Please try to stay warm.
