    Dears,

    I have my engine posted at Florida AME since 2008.
    I would like to share with you the following:

    First o all I do not want to bother you asking many questions about my Little Angel; however I know we like this hobby and so I encourage to ask you the last issue regarding my engine in order to finalize it.

    My engine sometimes start very easy spinning by hand the flying wheel and sometimes I need to use a starter motor to do it.. After some attempts the engine running for about 15 to 20 minutes as a hit and miss engine, sometimes it run as hit only for 15 t0 20 minutes. After that the engine stops running and I have difficulties to start again even though it starts for seconds and then stop fire.

    It is too strange an engine run then stop after 15 minutes.

    The Impression I have is that the needle of the carburetor is very sensible and any small adjust the engine choke or become lean mixture.

    I do appreciate some comments for this kind of issue. The problem is to keep the engine running for hours for instance.

    I do not know if this problem has some relation with compression, because I can observe that the compression is good.

    In fact that´s the last issue to end. I am still in doubt if the carburetor needle mighty be the problem.

    Again it is strange work well then does not work properly.

    Any help will be much appreciated.

    Once again thanks for your patient

    I posted on yuotube a movie in order to have an idea about the engine




    Regards

    I have built a hit and miss also.... i had a problem with the vibration of the engine causing the mixture needle to change a bit while running.... if thats the case the try putting a spring on the mixture screw..... it sounds a little lean from the video... if the intake valve has to opem more then once before it will fire on the hit cycle then it is too lean.... hope this helps.

    Dear Jason,

    Many thanks for your comments. Two weeks ago I have installed a spring on the mixture screw, I had a little improvement but the problem continue.
    I am still trying to solve the porblem.

    Regards

    These small engines were never designed to run for hours at a time, without some sort of cooling. I would guess that the piston is expanding and increasing the friction to the point were it is atually seizing-up within the bore.. You might try adding some coolant like anti-freeze in the water tank. Hope this helps. Be happy with it running for 15 minutes at a time....

    Dario,

    Thanks for your contributions. I think you are right this is a small engine with restriction to cool. I think the goal has been reached that is to run the engine.
    Nevertheless I am still trying to get it running a little bit more because I remmember that a member posted his Little Angel after breaking in running lot of time.

    Regards

    Ricardo
