I just installed the new ST carb on the vintage ST engine,and it fits well. It's a bit "tight" but it fits. Looking forward to seeing how the new carb improved the engine. I can hardly believe Super Tigre would keep EXACTLY the same size throat for the carb on its engines all these years.

. Last evening a freind and I did the fine tuning on the new G-series SuperTigre carb ordered for the vintage ST .56 engine. What a difference!!! We now have a reliable idle, and a much faster transition betwen idle and full throttle settings. The engine runs like "a champ", and I feel much better about flying it with this carb. Addition of the new ST carb, (that fits current and vintage ST engines .40-.56) is definitely the way to go.
I originally felt the new carb added a few hundred RPMs, (up from 10,500 on an 11X6 wood prop to over 11,000), but it appears I may have had it a bit too lean. RPMs are now back down to about 10,500, with the engine running slightly rich on the verge of a strong 2-cycle "whine". I believe the engine will lean-out further in the air, so the slightly rich setting makes allowance for this.
We're about ready for detailed TRIM flights to get the Taurus-2 back to prime flying condition. As I said before, the plane will only be flown under good weather/wind conditions.
I have asked SPA president and expert pilot Bruce Underwood to conduct a demonstration flight to put the Taurus-2 through its paces at the upcoming Asheville SPA contest July 18-19. I'm looking forward to a great demonstration, and a new video.
