I have a brand new YS-170 installed in an Astral XX. When I hit the starter to it today, it popped once and that was it. For some reason the engine has lost all compression. I changed the plug to see if that might be the problem, but the engine still has no compression. I was wondering if anyone out there has experienced this problem. I've had 20 or so YS's and this is the first time for me, so before I send it off to Richard, does anyone have any ideas at what I might look at?
Thanks
