Many things got in the way of progress but the build is on the move again.
That quote from rwm has had me thinking and the intake manifold I had built was kind of ugly and took up a lot of room so I came up with a new design.

I used an aluminum plate that bolts to the bottom of the head with a gasket and holes drilled in it that line up with the intake ports. The 1/8" pipe plugs close the off the two holes I drilled to intersect the intake ports. The carburetor port was drilled the length to intersect the far pipe plug hole. It is not real fancy but it works fine and shortens the over all distance from the carb to the intake valves by almost two inches. I had to move the gas tank forward and flip it around to get enough room for the carb.
My good friend Chris has modified a couple of R/C carbs for me. He is trying to get the venturi size smaller to closer match these engines and not the 10,000 rpm they were designed for.
We have been doing some tests with them and so far we haven't had a total success but we are still looking at different approaches and haven't given up.
The carb on the engine now is a stock one that has worked fairly well for some of my other models.
I may have a video of the engine running in the next couple of days if things work out.
Thanks for looking

New member here, but whilst perusing your shop, I see a rather large fan in the background. You stated you were making a work horse but never defined what kind of work horse. I myself being from farm country and all, seem to remember horses as being animals which were ridden, so that being the case, I think you might want to try incorporating that fan into this build. I see several options here with this combination. The first thing that pops up in my head is a parasail. Not the big bulky three wheeled buggy kind, but the ones you just strap on your back and go. Another idea would be an air boat, suitable for swamps, rivers and the flats here in West Florida. Or you could just scrap the fan idea and make something exciting with it, like a cabbage grater for making Sauer Crap (I think I spelled that correctly). ...Or maybe a jacuzzi bubbler. The applications seem to be endless. Wait! This build was probably over months ago, so I'm just wasting my breath. Oh well. As a new member I'm required to make three unlinked comments so really there's no harm done. However, if happen to read this and decide to repurpose your motor because of these wonderfully, ingenious ideas, feel free to do so. He'll, I won't even charge you. ...fr any of
Did I mention I'm a new member and am therefore required to post three posts for anti spam purposes. Oops! Yes I did. Oh well that's two down and one to go.
