What they said. I've found lint, hair, ghost turds, dirt and all sorts of stocking stuffers inside various carbs in the past when my engines were giving me fits. This is in spite of running a filter on my fuel jug and an inline filter before the carb. Somehow, that stuff still sneaks its way in there over time. Once, I had a brand new ST that I could absolutely not get adjusted right and ran unpredictable. Later that day after getting home, I yanked the carb apart and found aluminum shavings from the machining process inside the barrel. And this was one of the older Italian made versions, so I don't necessarily buy into that crap that the Chinese versions are any worse than the European ones.
Very true, I can't see a lot of difference in the CNC machines used in China or Japan. I have been told the metals used are different but haven't seen it as a problem. Quality control may be better in Japan??? As Jug pointed out, crud can happen no mater who makes the engine. I don't see a lot of the GMS or Tower engines at the field these days so can't say if they have gotten better or not, other then that run on problem the Tower engines ran very well but if you stuck a finger over the carb and it kept runing you knew there was a leak someplace. A very old post but it seems to have found new life!!
