I feel that it will more than likely be the plug that's defunct or carby issues. I just love what people say when they are selling something, the lame excuses and cop outs are just a whole bunch of cliches, a bit like a footy coach in the post match presso when they lost.
As far as the sprockets etc. are concerned it looks as if the main powertrain chain and sprockets have seen better days. This is the one coming from the top small sprocket on the PTO (power take off) shaft. The other one being the land roll clutch chain looks not to be in too badder condition. Lets put it this way, I've seen much worse and yours will carry one for a few years yet. Cost is a major factor when deciding how far worn an item is as it's going to inflict pain into the hip pocket.
One thing I would check very thoroughly and that is any signs of rail fatigue around the inner engine mounting bolts. I can't see properly in your photos but it seems there might be some signs there. Can you please give me a close up photo of the two rail mounting points which are on the inner side of the engine and not the outer ones which are nearer the side plate of the chassis.
You'll reel has plenty of life left on it as far as a regrind is concerned but I'd say the bed knife will require replacement. If you could tilt the mower back on it's handlebar and take a couple of close up shots of the leading edge of the bed knife so that I can assess it and advise you best.
Cheers, BB.
I live a 24 Hour lifestyle, but every now and again I seem to fall asleep, well at least that's what my wife tells me.
