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> <DIV> </DIV> <DIV>Larry</DIV></BLOCKQUOTE></BODY></HTML>
