Hi Troops,
I have a members 1986 226 here for much TLC. Primary problem was contamination on the carb and fuel system. I'm not sure what the stuff was that was in the carb, but it was blocking fuel flow thru the high speed jet. This is a B43M Onan 16HP, unknown hours as the hour meter is inop and reads 4,483.3 hours! Looking over this engine, it is evident that it is a low time engine/tractor, good thing!
This post will cover the fuel system related situations.

Pics of pulse hose on a B43M, B48M with Nikki carb and blower housing mounted fuel pump. On Onan powered 226, 446 and 448, the fuel line goes thru the hole in the crossmember by the fuel tank, passes over and behind the travel control valve and forward in the left hand side frame channel, by the lift cylinder and out to the fuel pump. I leave some extra length to allow for moving the fuel tank to access the fitting. About 8' of 1/4" fuel hose is needed to replace the fuel line from tank to filter, from filter to fuel pump and fuel pump to carb. The fuel pump to carb line needs to have a large turn in it so it won't contact the engine governor lever.
