Also let me stress that I do not mean briquettes when I say charcoal. I mean hardwood lump charcoal made from some kind of raw wood. Briquettes have binding agents that can burn incompletely and add crud to the gas.

This will be a dual fuel setup by the way, and my start-up procedure would be pretty simple. Start up on gasoline and let the engine warm up, then light my nozzle for the gasifier. Gas production would take less than a minute to be potent enough to run the engine. As soon as it starts sounding rich I would shut off gasoline flow and let the float bowl empty, while also closing the air intake. Woodgas has a different stoichiometry than gasoline so you need much less air, so you basically build an air mixer. Really is just some kind of valve that runs between the carburetor and the woodgas line. In theory this also means I could run on alcohol fuel without needing to increase jet size due to altering the amount of air instead of fuel.
I'll be sure to document the whole process so people can learn how to build their own, from making the fuel to building the reactor. Charcoal gasifiers aren't really a trade secret amongst Woodgassers and they are the easiest and least risky for the engine to build.

Well I've found my drive pulley. I work at a GM dealership and handle the scrap metal, they let me take little stuff that isn't worth much as scrap so I like to grab these alternator idler pulleys. I pressed out the bearings in two of them just now. 2.4 inches OD. With a 22" sheave made from a 26" rim welded to the other rim I'll have a 9.16:1 gear ratio. Think that would be plenty low for a Honda 196cc clone?
The bore measures 1-7/16" so I could weld this to a V series hub on the outside and weld a V belt for an alternator to generate electricity for my lighting and whatnot.

What are you going to use for a pulley to drive the big sheave ?, that's the pat that will slip. ...........Curt
I was planning on using that idler, I pressed the bearing out and I'll weld it to a keyed hub to put on the engine. I'll use another idler as my tensioner.
just to show you mine. My drive pulley.
board out to 3/4 the 5/8 to 3/4 bushing, alternator pulley, same as having 6 belts in one..........

I'll try to hunt for one of those smaller ones. I have some bigger multi V pulleys but the ratio would be too tall.
My rim pulley is a 20" bike rim 16" same as Whizzer pulley. mounted with tabs, had a 1/8" ring rolled.
I went to electrical mechanical shop that repairs and they gave me one.
If all else fails I'll just go chain drive with a cvt. It would help keep the engine in low rpm at least. I'm sure the gasifier wouldn't like being pulled at 6500 rpm or more the entire time.
Also here's the handlebars I made last year. They're sitting on the Seattle right now but they don't really suit this frame. Just 1/2" sch40 water pipe, comes out to 7/8" OD so it fits most motorcycle accessories. In the background is a nothing special 66cc build I did. Built from a Magna mountain bike frame, it's really tight in there. Runs great but the brakes are god awful so I don't ride it much.
I have a antique Lauson 4 stroke, not really high rpm, took all the tins off, this old fart is out for fun not speed..........Curt
Old fashion rope start, will have a later Kohler 3 hp carb for it. Original 1 3/4 hp, will have a little more with garb and exhaust change........Curt
That looks like a sweet engine. I need to start looking for older horizontal shaft engines.
Won't be much for speed 25 maybe 30 MPH tops here is my pattern, will not be a copy just my version of it. I do have another Lauson if interested........Curt

Maybe. Would look nice if I built up that 24" girl bike and I wouldn't have to worry about an engine being too strong for the frame. Fun little putting around bike.
Would .049" thick wall tubing be substantial enough for a downtube? I think that's 18 gauge. It's 1" OD seamless. It's what I had locally but I saw that some auto parts websites sell thicker stuff. I'm going to be notching the tubes and welding them instead of lugging and brazing.
