Kevin and @Bobmac
Happy New Year to you too.
I’ve never pulled the intake. Only the tb, because it’s so easy to get to.
If you scroll back 10 days in this thread you see the smoke from the resent intake burn 
The sooty throttle plate pic was from prior to that.

Big road + steep hill + heavy truck + small motor = hybriding.
100 mile roundtrip yesterday. Wife acts camera man.
On our way home we had two intake events. Cars behind us disappered in a cloud of smoke
Looking back in this thread I noticed last time I burned the intake was early December. Everyday DOWing ever since without taking a look at the butterfly. Not good. I decided for a fast swap to an already cleaned up throttle body this time and vacuumed the intake. The runners looked pretty good. Torch next time.

Ha, you need no “biochar” for your potato patch. Just shake off the TB on the rows and you good to go
But it looks nice and dry/flaky so thats a sign of a good sistem!

looks a little whiter than the char in my intake, though it seems as if its no hurting the motor, mine was a little bit darker, though i never got a tarry sticking throttle, so were in the safe zone for tar free wood gas design gasifiers.Are you burning a lot of pine through yours.

Haha, funny funny 
What I’ve found though, is that intake events are more likely to happen right after several short runs pullstarting the gasifier. What I think happens is fluffy soot gets covered with trace amounts of tary fumes and heavy enough to let a small flake of soot go.
Not a lot. I try to avoid both pine and spruce, but sometimes the size is just right for chunking and I can’t resist.

Coming home and shutting down yesterday I reached under the truck to give an annoying exhaust rattle plate a good beating. Doing so I grabbed one of the pipes going from the cyclone outlet towards the rear tank. Just as I grabbed it, it hit me - maybe I shouldn’t - could be hot. But it wasn’t - it was dead cold ??? Hm, plugged. I touched the other one and it was hot of course.
Being hot and dry I have never flushed these two pipes - in over 3 years and 16,000 miles. But I actually suspected something like this was going on because I lost my rail temp reading about a week ago. Plugged pipe below.
And @Jakob, reading about your melted rubbers. I wish I lived as close to @Wayne
Two feet downstream my cyclone I have a couple rubbers I patched up with silicone a few times. It’s borderline too close to the heat to use non-metal parts.

That plugged pipe looks like it could be a problem, LOL.
Yeah it is a blessing to live so close to good folks.
Jo any chance we could get a few pics that we can see the gasifier I think all that i have ever seen are from far away or real close up?

Ya those boots have seen better days, I’d like to find somewhere to buy bulk silicone hose so I could just cut them as needed. Might have to make some phone calls to my hydraulic supply guys at work, they may know where to get some

That plate in the bed is probably worth more than everything I own. That’s about the cleanest installation I’ve seen so far.

Tom, you’re right. The plate was expensive, but necessary for that pita inspection three years ago. As I mentioned at the time - not only women and magpies like shiny - so do inspectors.
I estimate I invested a total of $200-300 in the build - rubbers, clamps, some of the piping and the bed plate. On the bright side, that investment has saved me at least 20-30 times worth of gasoline so far.

Do have a picture of the used/dirty hay?
2 Likes
I’m afraid not. The used hay was black of course, softer and somewhat compacted, but otherwise not much different from fresh hay. I’m pretty sure I could have waited another year / another 6,000 miles.

So did you finally pass inspection with the gasifier in the truck, or are you still having to take it out?

Billy, you mentioned you’ve been out of the loop for a while, but not that long, right?
The Mazda gasifier has never left the bed. It was inspected and registered as a gengas-vehicle in Sept 2018. Post 248.
The Mazda being 30 years of age there’s no road tax and regular vehicle inspection only every other year. The gasifier is considered part of the chassi and included in the curb weight.
Insurance is $110 a year and avarage gasoline consumption is 10 gallons a year. 18,000 miles on the gasifier so far. It’s the most economical vehicle I’ve ever owned
