Hello, I’ve got a 66 Gravely L8. I’ve been haveing an issue where, when snow blowing, the engine easily get overwhelmed and will die. I am constantly having to pause and let it catch up. When I first got the machine 6 years ago it would chew through any amount of snow without any complaint. Wondering if anyone can point me in the right direction? I’ve cleaned the carb. Had the governor serviced. Neither seemed to help. Am I dealing with loss of compression? Any ideas would be appreciated.
