Hi chicken Maybe the amount of fuel that is injected is still too much. Try to reduce the stroke of the injection pump. As a guide line look at the injection pump that Hansen uses. It's very very small. And that has a reason. Where are you from? Stefan

I wanted to show the finished Engine in the Build thread but i found the thread is closed. So i post the pictures here. My finished Version of the Tiny I.C. originally designed by putputman. The engine has no classic carburator. It runs on gasoline Vapor instead. The speed can be adjusted by...

@kadora I know the guy who made the castings. It's a friend of me. We often build together. His name is Jürgen Bärenz as Werner already said. If you are interested please send me a Pm. I can make contact for you.

Hi Here's a little update on the progress. I decided to build the Tank and post a picture rather than drawing it first. I also finished the exhaust with the flap. These little parts took me almost a day to build them. Stefan

Hi Gail Thank you very much for the nice drawings. I appreciate sharing the drawings and i`m sure they will help me a lot. I´m just brooding here about how to design the Tank/Vapor Carb for the Tiny. Have to keep in mind that the Carb needs about 15 to 20 cm² (gas)surface to work and vaporise...

Gail That would be nice. Thanks a lot. I still have a lot of work to do on the Tiny to make it look good. The exhaust flap is one of the latest things i can do. Stefan

@ Gail I´m just watching the pictures on post #128. The neat exhaust flap you made ! I like it very much and want to build one for my Tiny. Can you please give me an idea on how you made these parts? Stefan

Thanks a lot. The Vapor Carb i used for the Tiny test run is from another engine. I attached some Pictures. The dimensions i used here: The Glass tube has an inner diameter of 22mm and 24 mm outer dia. and is 80 mm long. it is glued with a loose fit to the aluminum side walls with Loctite 648...

Hi together I have good news. I finished the new Sparkplug, put everything tentatively together and gave it a try. I don`t use a liquid gas carburator, cause they are difficult to build in these small dimensions. And they often make problems. I use a vapour carburator instead. What can i say...

Hi Jim , Gail and Arv Cleaning the Plug with brake cleaner was the first thing i did, but it didn`t help. I remember, as i turned the corian insulator, that the thinnest part (2mm) broke off. I glued the parts together hoping it might work. But as Gail already said, a little crack in the...

Hi A little update on the progress. The new Conrod is finished and i made a new piston with a tighter fit as well. It is about 0.04 mm (or 0.0015 inch) smaller than the bore. Tried to start the engine but no success! It sure popped a few times but it didn`t run. I found out the problem is the...

Hi Gail Well i`m glad to hear that leaving the pin floating in the piston is no Problem here. If it works for you, it`s goin`to work for me too. :) In other engines i used to hold the pin in place with a little M1.6 or M2 screw depending on the size of the piston. Because i converted the Plans...

Hi together At the moment I´m building my Tiny and it`s almost at a stage to let it make the first few pops. But i have a question left over. How do you secure the Piston pin and prevent it from making scratches into the cylinder wall? There is no room left inside the piston, cause everything...

A friend of me and i build 2 of these nice engines. They look 99% similar. We used castings from another friend who made them for us. The engine is no hit'n miss. We use 2 driven valves instead. We gave it an adjustable ignition which is not really necessary but looks cool. The ignition system...

This is my version of the Jan Ridders 1 Cylinder - Glass 4-stroke Gasengine with rotary valve. The engine runs with the Vapour "carburator". By having only low power the engine still runs very good. While running you can see the combustion fire inside the Cylinder. Very cool! Original Plans on...

Hello Guys I´m new here in this forum and i was reading this Thread with much interest. Today i received my IGBT order and breadboarded the circuit. I saw that some folks here in Europe have trouble finding some parts. I didn´t have the 2N4124 Transistor here, so i used an easy to obtain BC 547...
