Funny Dave l was wondering the same thing. Last l heared from @ramosedmundo he was working on a nice truck he wanted to DOC.
If he doesent respond, l will make the drawing. I shuld make a report and walkaround too, but l wuld like to finish it all first. The Mercedes is in a driveable state but far from finished. Still missing some vital components like a fan, automixer and all instrumentation.
I had problems with constipation lately. Dust formed a inpenetrable lair on the grate that was even hard to poke trugh with a poking rod. The grate l had has prooven ineffective for shaking out dust, char filled the tracks and it got stuck. I made a new one, a circular one that fits loosely in the restriction, resting on a center pin. Similar to Pepe’s grate. It rotates and slips char nicely only when rotated.
Yesterday l installed vacuum lines, hooked up to hopper and gas outlet and started the system. For a test l built a simple hose manometer. The vacuum was much less thain expected. The engine run poorly too, having trouble runing above 3000rpm. The ashpit guage showd 10" max but the hopper/ashpit ratio was more like 1/10, if not more! I went back and rotated the grate a bit, sliping maybee a pint of char. Vacuum went down to a healthy 3/1. So, thats setled. I just need to make the grate shaking remote.
But the car still run crapy! Idled rock solid but didnt rev. I went in the front opening the filter and boy what l found. The filter sack was partly burryed with dripping wet dust! I took it out and tryed runing the engine for a few seconds without it. Nope! Still no better. Vacuum the same. But this is a proove that even in the worst case scenario the sack is breathable!
Then l let the car idle at 2000rpm for a minute or two, closely monitoring the vacuum guages. I saw a occasional distortion in the water level. And siting in the drivers seat, l culd hear the engine hickup slightly at that point, and the car moving slightly, like if someone leaned on the car door. Listening even more carefully, l culd hear a “gloup” sound under the car. Aha!! This for sure means water in the cooler/gas suply.
But where did the water come from? JO sayd yesterday one of the members of the Gengas meeting sayd there are usualy 3 gasifier problems. LEAKS, LEAKS and LEAKS. I went looking for them and l found a pinched seal on the ash cleanout door on the ashpit! It seems a part of the gas burnt in the ashpit forming water that condensed and accumulated in the cooler.
So the plan now is take the system apart, clean it all and fix the leak. Then go from there.
