I found this STIHL BR 400 on Facebook Marketplace for only $70. The seller said it ran last year and thinks it's only a carburetor issue. I just fixed a BR 400 last week and have an extra carburetor and a few other parts. Should be an easy fix right? Although this is the same model I fixed last week, it's not the same problem.

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.
