Bonjour Roger,
Many thanks again, this link will also be useful for lot of members.
Hi all,
I got my vertical ET1 some weeks ago and i did some experiments on it. After replacing the piston rings and re inserting the crankshaft it started only withe a rope.
My mistake was, i didn't pay attention for the timing of the exhaust valve. The valve should start opening close before the bottom dead center. The ingnition should be short before the TDC.
After all i need only one turn by hand to start reliable. Depends on your needle valve. 1/4 Turn open. Eventually you can choke the Carburator with your finger.
Excuse my poor english.
Greetings from a hit&miss guy
Thomas
