Here is a pretty good Magnum XL 28... it was dirty but looked like it wasn't run too much .. it's had at least a gallon of fuel through it .. being an ABC engine means it wil last quite awhile,... The inside wasn't that dirty and the crank was still shiny .. the bearing were pretty clean too .. .The carb barrel was taken out and polished .. all the screws are still original.. the muffler is clean... I polished the head, crank and cylinder ... it took a bit of patience to pull this little gem into bits .. I cleaned the top of the piston the BP gasket was intact.. it's clear plastic ... both bearings were good ... if you want new bearings .. install them before running the engine .. it will come apart and go back together easier .. it took some heat to install the rear bearing .. glow plug is good .. compression is like a broke in engine .. with an hour or so of run time ...
