Thank you @shastonian_74 for a great business transaction. Chainsaw delivered as promised, constant communication throughout the process, and for standing behind the product in case of issues. So far, no issues whatsoever! Got the carb replaced with DM13B as recommended and muffler changed to 5100 version without cat. Runs like a dream. Idle around 2600-2800 and max RPM set to around 13,500. May raise closer to 14,000 once I get to actual wood.
