Qualcast Suffolk Punch 30s Self Propelled Cylinder Lawnmower , Non-runner

Qualcast Suffolk Punch 30S Self Propelled petrol lawnmower complete with grass collector Was working fine previously but suddenly became problematic, it would start normally but then when it warmed up the engine would race away and rattle noisily. It s been sitting in a dry storage shed since last year, the engine turns over by hand and seems to have good compression but it wouldn t start when I gave it a few pulls this evening.  Selling as a non-runner - spares or repair , no return Collection only, from Acle , Norfolk
