It's actually a Wisconsin-Robin, made in Japan. Only supposed to be rated for something like 4 hp, but it does way better than I expected it would.
There might be enough room to get a loop in there. The gas line is only about 2" long and there is probably an inch or less between the nipples on the gas tank and carb. i think the line is supposed to be metric, too, because 1/4' line slips on really easily and it needs hose clamps to keep it from leaking.
I don't know how that engine came to be on this tiller, as it was on it when I got it. The gas tank and carb were off and the fuel line was missing, too, so I don't know how the fuel line was originally supposed to run.
Here is a slightly better shot of the engine, though not the carburetor side. It is actually a pretty nice, apparently well-built little engine.
