the oil in our engines. Charlie's valve cover had no oil at the
NATS. I don't know about the fuel we are using, it's the same you
use. Let me know what you find out.</FONT></DIV>

color=#8000ff size=2 FAMILY="SANSSERIF">Before the Nat's I completely rebuilt
my 140L ten or so twelve minute flights before departing for Muncie and
another ten or so flights prior to the start of competition six single round
flights at the Nat's. After returning home on my second flight the engine
sagged on my second time through the advanced pattern I was running a 15.5x13
APC prop and 30% nitro the engine turn's 8400 rpm. Today I went to the field
and because of the wind changed to a 16x10 APC the same as I did in the wind
at the Nat's the engine turned 9000 rpm and ran fine through the first time
through the pattern and then sagged, the engine never quit but I landed to
check it out. After refueling I started the engine and it acted like it was
very rich but got hot so I shut it down.<BR>Thinking I may have a valve
problem I removed the valve cover to check it out and found that the entire
assembly was dry, in fact the valve cover that was thoroughly clean and dry
when it went back together after the rebuild was perfectly clean and dry (no
oil on it at all).<BR>I suspect that the valve train is not being lubricated
and after the engine gets hot the valve train is seizing up.<BR>Has anyone run
into this problem or anything else that could cause such a problem?<BR>Buddy
