Yup, I have to be careful not to get the two mixed up! When got the 40cc first, I kind of freaked out and thought there was no way it would fit in the DVII. "After further review", though, and with the lucky purchase of a 34cc, I realized they were the same size externally. Speaking of lucky, this weekend I got an unrun Ryobi 26 4-stroke at a local garage sale for 10 bucks. Another project! I may be becoming a 4-stroke gas addict.
