Your careful explanations as you go each step in the removal of the U20 are very helpful. Already looking forward to your next video when the disassembly begins. The hot temperatures there should give you an idea of how working on a 311 is here in Texas!
Excellent explanation of U20 diagnostics prior to removal -- looking forward to the next episode when you remove it and the disassembly begins. (p.s. Where is your "little assistant" featured in your previous videos?) 😊
