Perfect Harvest

I bought a used, non running T540xp a few weeks back. I got it running (the impulse line was off the nipple on the case).
The only way I can get the throttle butterfly and strato butterfly to work decent is to flip the linkage rod going to the strato 180 degrees (not end for end), from how it came (and from the few pics I found online), but then the strato butterfly would only open about 1/3 at WOT. I took the linkage off and bent it a bit, now it opens maybe 85-90%, but doesn't start opening til the throttle is almost half open. I've ran 2 tanks through it this way and it seems to run ok.
So my question is, should the strato butterfly match the carb butterfly from fully closed to wide open?
Thanks for your time!
