Thank you David , Steve and Flying pencil, in the other side of the world
Being novice in this type of engine , not easy here in Belgium , where i feel very alone ,
i am now trying to find informations about a test propeller to run the engine on a stand , size , number of blades and so on
I have gather some period leaflets near Avialog , but not always easy to understand American english,many technical words are unknowned for me,
also i find difficult to understand how to ajust exactly the camshaft disc with the accessory case to have a correct setting
I will contact you David , many thanks
I have learn also that in France many Morane Saulnier have been remotorized with the W670 ,in the sixties , now called MS 317 ,easy to find on the net
You might think that i am crazy , but when removing the first cylinder, i had great difficulties to remove it , playing several hours with levers , screwdrivers , wood block and hammers and so on , then i decided to use compressed air and protecting carefully each cylinder , it did work perfectly without any damages, they did land safely in the soft grass in my garden , see https://www.youtube.com/watch?v=8taWa2kT67c :love-struck:
Thanks again
Have a nice day
Roland
