My next plane will be a Dave Patrick Extra 330L and I'm trying to decide between a Saito 180 and a YS 140. I presently have a couple of 180s and like them very much. They are pretty much hassle free and low maintenance. I've read all I can about the YS 140 and think its a powerful well built engine, but all the talk about adjusting it and getting the fuel tank set up and adjusting the pump and setting the idle, is putting me off. Is it really that much hassle?

Also, whats the main difference(s) between the YS140 sport and the DZ?

Any help on making this selection is appreciated!
