I uploaded the video on my youtube newly created “channel”. Sorry about that.
I dont know about the design plan photo you showed because i do have jets going to the heart of my gasifier. Definitly not a downdraft.
This is the smog pump i used.
Cardone 32-3500M Remanufactured Domestic Smog Pump https://www.amazon.ca/dp/B001C9VOSU/ref=cm_sw_r_cp_apa_i_BAWtCb7FFRB59
However i paid 60$ and not the price showed.
I would have to check out the amperage with a multimeter because i cant seem to find it on the piece or on amazon site.
Smog pump are amazing but do take out the filter inside because it will jam in the motor blades at the first back fire.
I managed this build in a couples of months and i am very proud so far. I would say that it was hard not to go work on it during xmas period… and i have a lot of -20c days witch forced me to stay inside.
