You guys might both be right. I kind of get the impression that tuning issues are proportional to the displacement of the Super Tigre in question. I don't see a lot of complaints about the .34 through .75 models in the engine forums; it's the .90 and the G-2300 (1.40) that draw a lot of conversation.

My G-61 ringed has been a pleasure to break in and tune. I'd like to try some of the G-40 and G-45 models, but I already have a bunch of nice engines in this size range. The smaller Super Tigres are very inexpensive, very powerful, and very reliable by most all accounts.

For $84.99, you could try the G-61 out and sell it for 75% of it's retail price if you decided you didn't like it. If your Super Tigre G-61 ringed engine runs like mine does, you wouldn't even want to sell it for $100 once it's mounted and broken in.
