Been surfing the site, nice. I acquired this unit as is. Told it ran when parked in Sep. 08. Well I pull the plugs put in some MM oil and let it set. Put the power to it and click. Oh well grabbed the flywheel and it moves only about >1/4". The pistons are both moving up and down with the little turn. The advice I need is to figure out if the engine or the shaft is locked. What would be the best way to do this. Of course the PO knows nothing about this. The way I look at it is I got a trailer to haul the golf cart on (ha ha). Thank you in advance.
