eddy performer probs and question

cleaned it up good and set the floats. no more gas leak or bad idle. still has a little dead spot when you ease on the throttle from idle but other than that it does great. maybe need to change the step springs. has the factory "economy" jets in it. put about 100 miles on it last night mixed driving and playing a bit and got 15 mpgs. figure with a little tuning it should get a little better. still have the 2something gears in it. thanks for all the imput.
