Thanks people! These are the things i want to hear. I have a vp30 to use if I need to, but would rather not if I can get away with it. On the Funtana 90, the cg shift during flight does not require a trim change, so I don't really notice it. I am not after 3D with the 2300, even though it's on an F90. I will be putting it on a Goldberg Sukhoi after I am sure it performs up to my expectations. I really like the engine alot. Flying behind an 18" prop is fun, to say the least. I will be changing the fuel line to large before I fly again, and i'll make sure the clunk isn't too far back. If this doesn't quite get it, I'll add a one way valve in the pressure line from the muffler. At least I know now that what I am asking from this engine, others have achieved. Thanks again!
I have tried the "one way valve" from the muffler to the tank as you mentioned but my engine got very strange and was impossible to tune properly. Have you had good luck with "one way valves"??
Reducing the innerdiameter in the throttle barrel by putting a sleeve in there is a good way for better fueldraw.
Nope, never tried a check valve. I've only heard of them being used, never seen one. I think my particular problem could be associated with the medium fuel tubing and perhaps the clunk being too close to the rear of the tank.
I'm not into modifying carbs. If the stock one won't work, I will go with a Perry. I have had good luck with those, but I think the stock one is a much better piece.
