    PISTON AND CYLINDER SIZE. (O-Rings)

    Hi In my judgement all IC engines should ever have Metal Piston rings. Just to avoid the said Problems. In the end you will have to constantly change the Viton Rings due to wear. No matter how polished your Cylinder surface will be. This does not happen with precisely made metal rings. The...

    Upshur's opposed twin engine

    Dear Mr.Rupnow What's up with you? At first you are crying around cause you can't get your engine to run. You never take the advice you have been given from other builders. You ask for help but always do your own Thing. You tell us day by Day about simple things you get stuck with. A lot of...

    Tests of CDI Ignition Modules

    Gentlemen I wonder what this thread is about. It started good as a thread about testing CDI devices. And Now it drifted away to a philosophical thread about the natural wonders of the Universe and the mysteries of Electronic in specific. I thought it could be of interest but Now im out.

    Tests of CDI Ignition Modules

    The Metal parts of the elbow cap as Well as the Metal "shielding" around the sparkplug wire is the only ground connection of the whole CDI ignition. RCexl and most of the other manufacturers build it this way. If you remove all that and fire the ignition you will most probably kill it, because...

    Hi Giel The Links to the Websites you Provided are already ancient. And so are the ignitions. And most of the members here should already have seen them. Either they are way too big to fit in a Model engine or they simply dont have what has already been discussed here. Im interested in the...

    Mini diesel engine.

    Pirmin! Komm lass gut sein.Nicht aufregen. Du hast ja recht, aber es nützt nix diese Deppen hier zusammenzuscheißen. Das kapiert die Sorte von Leuten eh nicht. Ich hab auch schon was gesagt, hat aber auch kaum Wirkung gehabt. Am besten du ignorierst die, das ärgert sie am meisten.

    Mini diesel engine.

    Hi together I also built an Injection pump for a small Diesel engine. I used the dimensions that Hansen told in his Video. So its very small. I can Tell you that any Kind of o-Ring, be it Rubber or plastic does not work at All. It can not withstand the necessary high pressure. I could reach...
