Victa Tornado T4S484 (400, 4 Stroke)

Sorted problem , runs awsome again – my tornado was awsome to start with then started blowing black smoke couldn't figure problem out , thought there was only one filter . Problem solved found another filter that was completely blocked cleaned it now runs like brand new again .i thought the only filter was at the eccelerator there's also one right on the carburettor if your 4stroke mowers running bad check the filters
