<BLOCKQUOTE style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid">Side mounted NC's required a minor mod to the rear gasket of all things. A small notch in the gasket (which was eventually put into production) prevented fuel from loading up one chamber while at idle on it's side. Made a HUGE difference once I "snipped" it.

I know yours runs well, and I believe Randy Wolf ran 120NC's also when he was competing. But I also know that mine, and apparently many other others had a problem running rich on the low end, and the usual fix of drilling out the air bleed hole did nothing to fix them. Side-mounted engines seem more suseptable to this problem than upright or inverted. Mine was side-mounted.<BR><BR><BR>"Thomas C.

They are not as powerful as the newer models, but they are easy to run and so far, very reliable. I have only done the minimum maintenance on then. Great for sport engines. I got rid of my SC's. They were the worst of all YS engines. I also agree that the YS120FZ will suprise most with it's power and ease of use. I have 2 of them and won't give them up. The 140FZ is great also.<BR>Tom Weedon<BR>-----Original Message-----<BR>From: discussion-request@nsrca.org [mailto:discussion-request@nsrca.org]On Behalf Of Bob Kane<BR>Sent: Saturday, May 17, 2003 3:58 PM<BR>To: discussion@nsrca.org<BR>Subject: Re: re ys 1.20<BR><BR><BR>Best to worst big YS four strokes IMHO, in terms of reliability and ease of use:<BR><BR>YS120FZ YS140FZ<BR>YS120AC<BR>YS120FS<BR>YS140L YS140DZ<BR>YS120SC<BR>YS120NC<BR><BR>I own or have owned the 120NC, 120FZ and 140FZ motors, and have direct experience with the L and DZ series.
