I drained the tank to see if there were any clues to the ongoing rough running and backfires. A small amount of water, a lot of rust and something that looked like algae came out. Flushed through 8 or 9 times and blew the petrol pipe back from the pump. None of this debris has ever reached the pump so the tank filter must be intact ... but possibly blocked!
