I started on the coal gas very easily. (This engine is not running very well with gasoline).
After 20 to 30 minutes of operation, the hopper was nearly empty.
Can I recharge the charcoal into the hopper without stopping the engine of my tractor?
I have some pictures. I will try to load here if I find how to do this.
I had to immediately share this event with you.
Hello Trigaux
You should be able to reload while idling 
Bravo Trigaux, bienvenue au club des mains noires ! Si ton unite est un “updraft” tu dois arreter let moteur pour Faire le plein.
Encode une fois bravo

Bienvenue Trigaux,
What a neat looking small dozer and running on coal gas,too. It’ll be nice to see pics of your build.

What a fantastic looking unit you have , makes me wish we had kept our little crawler now .
If this is charcoal unit then as far as I am aware you have to stop engine to refill your hopper . but it will restart almost immediately once the lids back on and the air is sucked out of the hopper .

I am very surprised at the engine operating smoothly. This engine has made backfier gasoline. I can not adjust the spark advance has.
(No landmarks on the crankshaft pulley, this is no longer the original pulley, I think)
Coal was burned very quickly. is this normal?
Aproximately 20 liters of charcoal 25 in 30 minutes
Charcoal is made of spruce wood
I will post more pictures tomorrow
Thank you for your encouragement

Hi Trigaux looking at your charcoal it seems too big. Shrink it to nothing bigger then 3/4" no smaller then 1/8th with a good cross section of all sizes. I think you are getting too much CO2 escaping un converted hence the short run time beautiful build though
David Baillie
That’s roughly 3-19mm for those of you who live in countries with the superior measuring system. 
thank you David for the remark.
I sift my finer coal for the future
