I have a 170 that is a powerhouse when it starts. My problem is that it is very hard to start on the first run of the day. After that it is no problem. It seems like it is not getting any fuel. I crank and crank it wide open and no fuel fuel even runs out of the muffler. Then sometime during the cranking secession it hits and starts.
This is my first YS engine and I do not understand what the problem is. ( never had any problems with my OS motors )

Which direction do I adjust the regular again? Turning it clockwise richens it. Is that the way I should go? ( One full turn or what )? It is flush now.

Any help would make my flying more of a pleasure rather than...( hope it starts or how long is it going to take to get this motor to fire )!

Any tricks that I need to know would also be appreciated.

OH... using CP 30% fuel.
