As regards the question posed, if you want to stop your clunk coming to the front then you can include a short length of brass tube in the line from the bung to the clunk. Leave a flexible length of tube at each end so the clunk still falls to the bottom of the tank so that the fuel feeds but include enough brass tube so that the pipe can't 'turn around'. Do I need to draw a picture or do you get it?
I guess I do need a picture
as I don't quite understand the process. A picture would be very helpful in this problem.
As for what mixture I'm running at, its a rich mixture becasue theres usually a stream of smoke coming out from the muffler at full throttle only though. Should there be smoke coming out even if its ideling or at half throttle? My last few flights, I didn't even touch the mixture setting and it has run better than ever, so even making sure that its at the right setting by doing the above methods of leaning it untill max RPM is reached and then enrichening it from there I'm afraid of doing because tampering with the mixture before has only made things worse and I don't want to screw up the good setting its at now. I'm still concerned with my ideling being to high though so I will try that method of the plane should not be moving on idel other wise its ideling to fast. I fly off a grass field, so I would have to test it on pavement I guess because sometimes my plane won't move at all even at full throttle on the field, I have to give it a little push it get it going. Its not grass cut for flying airplanes. I don't usually go to a club, I usually fly solo at my own private field. Its great because you get to land wherever you want to.
