One turn out is a good place to start.
If your not getting anywhere or it was firing and then
your not getting anything. Close the mixture screw and
try to start it. If it does the mixture screw was open
too far. (flooded) If it just pops a time or two and then
does nothing you need to open the mixture screw another
1/4 turn. It will be easier to start it out of the water
as they don’t pump water anyway so it wont make any
difference if the exhaust valve is open or closed. When
you get it on a boat you’ll want to open the exhaust
valve when starting. The purpose of the exhaust valve
is to let air into the motor to start it. Air cant get in
if it doesn’t have a way out.
