Hi Speedy, as Ted says vibration is the most likely cause. It certainly is Chinese and if it is a Tornado then those bases are a bit prone to that cracking, they seem to be thinner, used the same amount of steel as the standard PT base but stretched it a bit further to make it the 19 inch. If you fitted it to a standard PT base you would need a 20mm spacer under the motor because the shaft is longer. I'm not sure if the spacer ring used under the Briggs on the PT bases would fit the bolt pattern but I think it should. I can check later if you wish. Like you Speedy, I have trouble sleeping
Merry Christmas all
