OutdoorKing Repair Forum Forums Restoring, Customising and Modifying Engines Boundy BMS Engine - What's Inside?

Good Afternoon ODK Members,

I have been restoring a Boundy Lawn Scout and as always I pulled down the engine to have a look at condition etc. Now this one I have had running but only after removing the air cleaner and muffler, I figured the seals were probably hard and the rings a little worn.



I found the crankshaft was cracked right through, I would say that the magnet had worked its way out a little and was picked up by the the inside of the crankcase.



I have a spare crank which is lucky, pays to have a look inside. The base is ready to go once I get the engine sorted. Bearings and seals are from the local bearing shop and rings for this model are the same as JAP Model 80.
