Wondering if anyone else has ever had this...... I have a DLE 55 in a plane and have been flying in wonderfully. It has very little burble and runs great. The curious part is that if I find the right spot on the throttle where it has a little burble, then flip the plane inverted, the burble stops completely and it purrrrrs like a kitten.
Any of the pro's care to lend a thought?? My other 55's have no burble at all. Thought maybe the input on this may also help some of the guy's trying to tune their 30's.
Thanks!
Terry i'm no expert but have you got a tube running from the diaphram cover to a bottle inside the fuse? Sometimes the atmospheric pressure can add more pressure to the diaphram in certain cowls and this seems to take care of it.
Here is what I have done to all of my gas engines.
