I picked up a used, near new condition Stihl HT-131 (4-mix engine) pole saw for $200, yesterday. I was discussing fuel mix with the previous owner and he was telling me that he likes to use 20:1. Stihl specifies 50:1 and it goes against my grain to deviate from manufacturer's engineering specifications.
I checked the plug in the machine and there is no fouling.
My (probably stupid) question is; aside from fouling, what are the downsides of running such an oil rich mixture? I expect the engine would not achieve peak performance and that starting would be more difficult? Having never deviated from fuel mix specs, I would appreciate comments from anyone who has first hand experience with this type of situation.
Thanks.
