<DIV><FONT face=Arial color=#0000ff size=2><SPAN class=150564502-29042003>I
have just found a problem that I'm sure many people on the list have solved
before. Often while doing a stall turn, my engine would stop
and a dead stick landing would follow. After discussing this with a
friend at the field it was suggested that it could be a fuel tank
problem. So I took the tank out tonight to have a look. With
fuel inside I could see that when the tank was inverted as in a stall turn
manouver as you go over the top, the clunk would often rest against the
side of the tank. So when the nose is pointed down, the clunk could
hang at the aft end of the tank but the fuel is at the nose.

<DIV><FONT face=Arial color=#0000ff size=2><SPAN class=150564502-29042003>I've
changed the length of the tubing (shorter and longer) and even added a
wheel collar to the line at the clunk, but so far I can't tell much
difference.</SPAN></FONT></DIV>
