Been down with the flu last couple days. But Nick, this is a Kuhl blower adaptor beside a regular blower carb plate (This one is a rough casting needing cleaned up before use, but I have 3 of these things, the other two have Mike Kuhl cast into them as well, I think this one was made after he sold the shop that was subsequently padlocked by the Sheriff's Dept on the new owners)..... He made them for both Dommy's and 4150's so they could be mounted inline as part of his River Rat package.

Obviously, center to center spacing is a TAD different, as are the overall dimesions of the original Dooley Scoop, which Terry has the only one I know of. I thought I had one found in Havasu, but nope.
