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 rev-up. 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 "NON-CORROSIVE". Now it says "CORROSIVE", "do not user on Aluminum". It now damages most carburetors.
