Gas Carburetor – woodgas, chargas, producer gas

Most people simply attach a tee to the air inlet of the engine’s carburetor. There will be a choke valve on the air inlet side that adjusts the fuel mixture. The other opening of the tee is the fuel inlet and the third goes to the carburetor. The advantage with this method is that the engine can be dual fueled with gasoline.

I have made my own carburetor but that is time consuming.

For a nice clean setup and no need to buy a mixture valve, because the original carburetor choke valve is used, is to modify the original carburetor. See the below video and photo. The fuel inlet is a reused vitamin bottle. This is were the fuel line is removed and the draft fan is used to start the gas producer.

First Small Scale TSI Machine

My first small scale skidding was accomplished by using the stock sleeve on the Wheel Horse. An attachment was made to lift the log somewhat. See photo above.

Wheel Horse fueled with charcoal and skidding a log.

Later the stock sleeve hitch was remove an a 2″ receiver hitch was installed. Next a winch attachment was fabricated and used. This allowed the stem to be lifted higher and more could be skidded at one time. The winch helps to reach stems that you can not back right up to. See photo above and photos below.

Version 0.3

Above is a photo of version 0.3.

Below are two photo of this early design on a Wheel Horse. The black plastic bucket is the gas filter. The last photo shows the converted engine and functioning gas producer. This Wheel Horse is now fueled with charcoal. There are two important issues that need to be correct in order for this to function. The first is that the charcoal needs to be 1/2″ in size and less. A lower percentage of 1/2″ size is better. Second issue is there needs to be no air leaks into the system.
