Problem with these mowers, not worth the time trying to fix, if after a carby clean and it doesn't want to play ball, down to the tip, even if after you spend a bucket of hours and go it working perfectly, what are you going to get for it, maybe $50. I was at Trash and Treasure a couple of weeks ago and a bloke had 3 identical blue mowers, I had a quick glance, they looked brand new, I didn't bother asking but they all had a tag on them with $50 on them. Makes little reason to bother fixing a mower these days unless it is a collectible one
