Riverview M-2 Mule

First attempt at starting the M-2 Mule and it was a success ! Watched the Thrive off grid YouTube video and followed the cold start procedure. I’m using oak charcoal the size of quarters and it was really easy to operate.Cant wait to hook It up to a 5hp motor soon.

Yeah be careful when opening the hopper lid after it has run. The hopper gases are combustible. When the lid is opened gas escapes while fresh air comes in. Once to the rite mixture the ambers can ignite the gas and come pluming out the top. Sometimes there is a bit of a delay so give it 10 seconds after the lid is opened and let this gas out.

Ok,I remember some of the forum chats and videos mentioning that.

Yeah we are working on a warning label that we will cut with the plasma machine. This will be bolted to the lid.

8hp Tecumseh running on wood gas.

Ok,first time attempting to run a electric start 8hp Tecumseh Snowblower with a M-2 Mule RTR.I decided to use this motor because of the electric start option.I started the Gasifier from a cold start by following Thrive off grid YouTube channel cold start video,as soon as I had a strong flame I turned off the blower closed the large ball valve and started to turn over the motor with electric start.By adjusting the air mixture valve and turning over the motor and it started to slowly combust the gas and after a few misfires it started running in less than two minutes ! I was astonished ! Made a few more adjustments with the water needle valve and air mixture valve and the 8hp motor was running strong,I even cranked the throttle up with the engine Governor.In order to have a strong air tight connection at the carburetor I custom made a sealed electronics box with a quick connect.This was crucial to have no leaks in the system.

Ok,I have practiced operating the M-2 Mule RTR from a cold start several times now and I’m felling confident doing that.The question I have now is does the flame need to hold steady before I close the large ball valve to bypass the gas to the ammo box filter and engine ? Or would there be enough of the flammable gas to run a motor with a intermittent flame that I need to reignite with a torch every 30 seconds to 1 minute. Sometimes when I practice operating the Gasifier I have a flame that does not stay lit and needs to be reignited and then sometimes I have a steady flame that keeps burning

My theory is that if I can ignite the gas with a torch regardless of how steady or intermittent the flame is,there is enough flammable gas for a motor to run on it.Anybody have suggestions would be greatly appreciated.

Thats just how charcoal is sometimes. There will be times it will light and stay lid and others where it will be strong but not stay lit. As long you are seeing a strong flare and you know when you have this. You are ready to run the engine.

Never try to run the engine with the Flare Cup valve open. Shut the blower off first as the winds down cut off the valve. Then with the mix valve shut pull the engine over a few times. This will prime the gas to the engine. Now hit electric starter and it should attempt to fire as the air in the gas bleeds out. Generally the engine will fire up and then gradually open the mixer valve. Once running give it a few minutes then slowly open it until you hear the engine rpm's drop a little. Then richen it up (closing the valve) until you hear the rpm's drop again. You should note these two points on the valve position as you do this. Now lean it back up positioning to the center of these two points. I generally will set mine just a little rich.

Ok,that’s what my thoughts we’re.As long as there is a strong flare,that should be enough gas to reignite with the spark plug from the motor.That’s awesome !

Im waiting for a few items in the mail so I can make a secure airtight carburetor adapter.And when I’m successful with that,I will make several custom adapters for various motors.Thank You !

That is so awesome. This is what the market dont seem to understand. You are not going to just buy other gasifiers on the market and do what these machines can do. These are true consumer grade gasifier systems.
