Run it on Stihl Ultra for more awesomeness. Pour in some Motomix (which contains both Ultra oil and liquid Awesome) and the saw will blind the unfaithful with it's absolute brilliance.
All said Stihl..Stihl.. Expensive but they are nice. My buddy has one that we have used for years. Great saw. What do if I have no possibility buy Stihl. I think why not Poulan pro like that ,I had a great experience with one of their trimmer (Hursqarna)and it also budget.
Bought brand new 362 for crew. Saw was always broke down. Had to hold down trigger put on break nose of bar in dirt and pull it and then that baby would run kinda decent for while could not get wood shavings to not jam saw up and take side plate of. Kept an echo timberwolf in truck. Had score board for summer and fall 362 always started the day and finished day headed to the shop to be adjusted. My 501p has little more top end than 362
