Look at the muffler.
It appears to be the same muffler for all.
That's not the difference.
HobbyKing offers the [link=http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=8987]ASP 1.08[/link] for $78.90 and the [link=http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=8988]ASP .61[/link] for $61.60...
Those offers for the ASP .91 at $103.85, or at $130.77, do seem quite expensive.
As Dar suggests, I bought the ASP 1.08 (2) when they were on sale at Hobby King. Mine were $70 each.

I looked at the 1.08 from HK and thought about it. The shipping comes out to about $35 so the price is higher than Hobbypartz. Hobbypartz is out of the 1.08. I found a place that lists the specs for the .91 and 1.08. There isn't much difference in stated HP. The .91 will fit the fuse opening better than the 1.08. I'll have to grind out about 5mm for the 1.08 to fit. I'm leaning towards the .91 since I now know the difference, I need to decide if I want the remote needle or not. Not sure if there is any running/performance difference between the needle locations. I just have to figure if I want the .91A or the .91AII since the only difference is the needle valve location. Maybe I should go with the remote needle due to missing part of a finger from a prop. LOL
As cheap as some engines are now days, if it's something other than bearings, they become throw away items. If parts are needed, it looks like Just Engines has parts but they are in England.
Here's a link to a review for the .91.

Thanks all. I didn't know the difference was the needle valve assembly.
