A friend of a fried dropped off a couple Stihl leaf blowers. He said the older BR400 runs, but is hard to restart and floods out. The owner purchased a used BR380 as a replacement to the BR400 and that one also don't run! Its leaf season and he needs at least one of them running asap. I thought this was going to be a quick fix, but was proven wrong. The BR400 was running well after tuning the carburetor, but now it no longer idles and the engine will not revup. Did I break it?

I no longer use Harbor Freight Super Heavy Duty Degreaser in my ultrasonic cleaner. Harbor Freight changed the recipe. The bottle previously stated "NONCORROSIVE". Now it says "CORROSIVE", "do not user on Aluminum". It now damages most carburetors.
