<DIV>As some of you may recall, I've been fighting this YS 61LS for about 6
months. For the last month, I've been able to get it started once and then it
would flood, with a river of fuel gushing out of the carb. Verne was
actually able to work with me and we got it started a few times in Dayton.
Using the same procedure he talked me through, it gushed again and flooded like
it just fills up the cylinder when I tried at home....</DIV>
<DIV> </DIV>
<DIV>Before I burn this engine up, I want to explain what I did as an experiment
and I'm considering running it to see if it will run with out burning up at the
low end.</DIV>
<DIV> </DIV>
<DIV>With the engine removed from the plane, I replaced all O-rings and gaskets.
Still leaks like it bleeding from an artery. I decided to connect a pressure
gauge and pressurize the fuel inlet and see if I could adjust the regulator to
keep it from leaking.</DIV>
<DIV> </DIV>
<DIV>Pressurized to 6psi. It finally stopped leaking at 1-1/4 turns in from
flush. Seems that it doesn't leak with the throttle wide open either. If I back
it off 1/8 turn, it starts to leak regardless of throttle position.</DIV>
<DIV> </DIV>
<DIV>In talking with Richard from YS Performance, it should be leaking at all
when set up properly. But I didn't talk to him about this kind of
adjustment.</DIV>
<DIV> </DIV>
<DIV>Question of the day...Since the regulator screw just so happens to
adjust the low end mixture as well, will I burn up the engine because it could
be too lean? Is it more likely that I have a damaged seat for the seal thus
leaking by at the "Normal" position of flush?</DIV>
<DIV> </DIV>
<DIV>I couldn't see any damage, but this is the only possible conclusion I can
make at this point with the results of my bench work.</DIV>
