RE: YS 160 DZ
Hi
This engine needs a powerfull starter.
I start it with twin turbostarter Kato and a batterie 12V. And I apply this procedure :
Open gaz throttle (without glow connect it's very important) and run engine with starter until fuel come in engine then I close gaz throttle.
Put glow plug and connect to batterie 2V, but I connect just a wire on batterie + or -.
I run engine with starter and put the other wire. It's easy with a friend who connects wires.
I did a lot of start (above 150 ) with this procedure without any problem.
