RE: 2C 91 engine
Hobbsy,
I guess I'm fickle, because after reading your post above, I went to marketplace and saw several ST 90 for sale and made an offer on one myself. Those prices were just too low to resist. BTW, I was very happy with my 61 and the 51 was pretty good too once I had it all sorted out.
I still think Supertiger can let some shoddy work out the door once in awhile.
