Hello All I have been given a brush cutter labelled Tanaka TBC-233 that doesn't run any more. I'm having difficulty finding any details on this model. It has a "different" (no gaskets, diaphragms or jets like the Walbro for a 230 or 232)style of carburettor marked O53B UI and what seems be a separate fuel pump on the bottom of the crankcase. Anyone have any ideas on it's "true" identity and where I might find some further detailed information. thanks Mark
