britbrat: you may have caught it, the left float is tipped a little lower in the front, not a lot, but it is there. They are very square otherwise. The wing seems dead straight too. My first thought was a leak in a float, causing a balance issue, but it balances out dead center. I am a machinist, so I have a pretty good eye if I know what to look for.

Thinking about it, I suppose the float tip could explain both tendencies I am seeing.

I Straightened the float out by unscrewing the rear pillow block on the left float and bending the wire down a little. Then I moved the block out a bit on the wire to compensate. Now the floats look very straight across their tops. Incidentally, when I dismounted the rear block, the floats wanted to straighten out, so there must have been some slight difference between my superstar and the plane these floats were originally built for, Or maybe thats why they were at the swap meet in the first place.....

This problem aside, this has to be one of the easiest conversions I have ever seen, I know the superstar is a popular plane, but what are the odds of buying a set of old floats on spec, 6months ago, and then finding the same model of plane they were built for at a garage sale last week??? The wires were bent to slip directly into the original holes on the fuse, and the front trike mount hole was off by less than 1/16"

I went ahead and removed the water rudder for now, I will add it back later if everything else checks out.

Thanks so much for your help!, I wasn't even close to catching this problem. Hopefully that is the extent of it.
