<DIV><FONT face=Arial size=2>Went to test fly the new plane today with the new
YS 140 DZ, but it wouldn't start. The started couldn't even flip it over,
and by hand it would go through phases of trying to fire every flip and not
firing at all. However, the really weird thing was that it would also go
through phases of just flipping with no compression at all, much like the prop
had come loose. We tried using the starter when it would get in
this phase, and after a few seconds suddenly the compression would come
back. After about 20 minutes of hand flipping it and not a single bit of
running, we went home and took it apart.</FONT></DIV>

<DIV><FONT face=Arial size=2>You serious YS guys will probably know what is
happening by now. Here's what we found: the nut that holds the intake
valve to the rocker that you loosen to adjust the valve clearance was totally
off, loose inside the valve cover area. The phases of no compression
happened because the valve had been held open by the nut getting in the
way.</FONT></DIV>

<DIV><FONT face=Arial size=2>Very strange that it would come from the factory
like that, but, put it back on and it is working fine
now.</FONT></DIV></BODY></HTML>
