Only when I am back seat driving. Lol.

Those videos always look like speeding to me. Like Bob, I’m always trying to steer and brake. Good thing you guys aren’t doing VR or I’d probably have a heart attack.
I guess the mother in law thing is the same the world over. When you get my age all the people that used to annoy you are mostly gone. Takes some of the strain out of living. Now if the grown up boys with more money than me would stop coming and taking my tools I would be an even happier camper.

Tom just start throwing hammers at them if they want your tools so bad. Works every time some of the time.

Bob, it’s accurate. The gasifier was pretty much idling.
Unfortunately cameras doesn’t pick up speed, inclines or even smells well. That would be something - now that it’s finally possible to run windows down, it would have been nice to be able to convey the wonderful combined smell of hackberry flowers, dung and woodgas exhaust 
TomC, she’s used to it. As long as we’re cruizing small roads like that, she’s ok. Entering a 70 mph freeway she starts acting the back seat driver as soon as I pick up the camera
Tom, really old cars used to have a hatch with a minimal back seat inside, close to the trunk. Over here it’s called the “m-in-law hatch”

I have seen her video work first hand, let her do the video recording, she is very good. My favorite is when she was video the dog in the yard, and then panned over at you filling the hopper on the Volvo with wood. You had this look on your face of a little boy in a candy store holding candy with lots of money in your pocket, has you where putting wood in the hopper piece by piece.

When you least expect it, first time for everything and all the rest of the sayings. Please watch the video and tell me if anyone had this happen before?
Sorry for what Cody calls JO’s heavy drawl, but translations require more thinking than talking

Good morning JO and thanks much for posting.
I think when the back fire happen your tennis ball valve may not have closed air tight and let just enough oxygen in to maintain a flame .
Edit ; I think a flame could be maintained in that area even if there were no soot and moist. Where the fresh air and gas meet after the ignition from the back fire .

Don’t be sorry, I like it!

Interesting the flame was able to sustain while the car kept running, I would have thought the gas would have burned up and choked the engine out

Hello Marcus .
I think if there had been a bigger leak it would have burned all or most of the gas then choking the motor out .
I think if the motor had been killed 1-2 seconds there would have been no issue and the flame would die .

The amount of gas that will burn is equal to the amount of air leaking in .

Thank’s much for the input, Wayne. Nothing beats real world experience. Makes perfect sense now that I think about it.
I suspect the broken, dried out tennis ball with rather weak springs probably didn’t seal 100% until under heavy vacuum. Also, the backfire flame didn’t necessarily need to have reached all the way down, but fire traveling backwards towards the air leak once it was lit.
Anyway, no harm done. The brand new tennis ball and piece of plastic already delivered another 20 miles worth of woodgas. No puffs!

That was very interesting JO. Could have been much worse because that plastic pipe will burn very hot. Could have set a lot of other things on fire had it fully ignited rather than just melted through like that. I had not understood about the tennis ball valves before.

Thanks Tom!
I don’t want to diminish the fire hazard, but I think as soon as I shut the engine down, the gasifier continued to produce a slight positive pressure, all the oxygen was pushed out and the fire was put out. Maybe different outcome if the plastic got hot enough to start burning on the outside

I always have a plastic jug of water and a fire extinguisher. Use the water first no sense using the cost of a refill.

It seems the Volvo is just returning the favour here. You fed it the good stuff, and in return its keeping your gray matter from geting stale and develop early dementia by throwing riddles at you
Interesting for sure. Althugh woodgas backfires do pack a punch. I have blown up filter cases before from backfires, when l had the filter close to the engine
