@EFIintegration You are totally right. There is absolutely nothing new or innovative about making something like this. Its just the little boy/girl in some of us that wants to make one for themselves. Unfortunately it isn't going to change the world. Hopefully there are some little boys and girls out there who start this simple and then come up with new innovations in time.
@turtlemann14 you can't use a smooth timing belt. It has a toothed timing belt. Can use a timing belt, gears or a chain to maintain a consistent 2:1 ratio between the crankshaft and camshaft. A timing belt is the simplest implementation.
@cffellows. As you suggest the throttle is just a simple barrel valve. Not included in the original design. It took 20 minutes to make and adds a nice degree of control.
As for the springs being flimsy I think they are adequate as the valves are tiny - the head of the valve is only about 9mm - and the travel is only a few millimeters. This makes them very light and therefore there is no chance of valve bounce. Stronger springs would only be indicated if valve bounce became an issue. Bear in mind that the engine is designed to run at slow speeds. It idles at about 400 rpm and runs at a max of 2600 rpm.
I have no idea what the fuel consumption is but it is very low as it runs off of fumes that get sucked out of the top of thge fuel tank. You could never use all the fuel in the tank as the volatility of the fuel decreases as the engine runs. To maintain smooth running the air screw needs to be closed more as it runs. Can't run it for too long as the spark plug is made from teflon. I generally run it for a max of 2 or 3 mins.
@darkprinslau If you Google "Jan Ridders", you can go to his web site and email him for a free set of plans. (They are all metric.) Pretty much everything is made from bar stock. Some builders even make their own spark plugs. He has a lot of plans available.
i can't see the tooth belt (timingbelt)
toothless is going to slipping the belt?

It took about 200 hours to make. Plans from Jan Ridders (ridders.nu)

could you tell me how much time did you spend making the engine?
where did you buy the plans or you designed it?

This is really cool but I though we crossed this bridge over 100 years ago.

Very nice running engine. Is that just a barrel valve you have for the throttle?

I would get tighter, progressive springs. Those springs look a bit flimsy to be running at that speed.

wow this is really a beautiful thing, i love it! I'm thinking to myself one to make. did you happen to have some tips or even building plans?
and which parts didnt you make yourself?
