[NSRCA-discussion] 2C 1.20 choices?

Mon Aug 21 18:41:02 AKDT 2006

Ed,
I had one of them babies and I had the opposite experience. The guys at the 
field all commented on what a nice idle it had, but I wasn't all that 
impressed with the top end, but I ran the stock muffler which was about the 
size of my bath-tub.
It sat around too long and the bearings went south.
