why didn't you grab me at the Shootout and I could have helped. Its very hard to help via the internet....yet I was there. I was screwing around with the boys and not really paying close attension to other guys flying. I know Bob Kane had lots of problems. I offered him a well tested and run 160DZ that was sitting in the box all weekend long. Instead he fought through several dead sticks. I offered the motor each time and he refused each time.


In any case as I said above the HS needle on the 140's is pretty broad and it will show the little to no change that you are talking about. As I said above THIS IS NORMAL. The HS will have little affect on the midrange to your ear...but it can if too rich on the HS cause the engien to load up and die in the mid-range. The HS needle works at all the settings not just the top end. This is why you should run in the leaner spot of that wide band you mentioned.

Also I mentioned above that you should lean the pump. The fact that you richened it and it didn't help is a sign it could have been rich to begin with.

I think you should lean the pump. CW about 1/4 turn and see if the midrange cleans up. This is what the pump does it controls the idle and transition though the mid range. So if you say its slobbery in the mid range then the pump is currently too rich.
