To finish the story (yes, a couple of years late), said carb that initiated this thread was for a snow blower. After borrowing an ultrasonic cleaner, and spending a few hours picking it up, getting u-sonic carb cleaner, tearing the machine and carb apart, and putting everything back together and returning the u-sonic cleaner, the machine started on a couple of pulls and worked fine. Then I searched on ebay for a used carb. Wouldn't you know it, there was a NEW Chinese one available for $12. Bought two and put one on my other Toro snowblower. Started on the first pull and ran like new. There is a lesson here....
