We have the parts list for the machine and also the general owners manual for McCulloch Trimmers. It is in the parts list and manuals area under question on Trimmers and brushcutters.
As to the fuel mix it is 40 to 1 using mcculloch oil but as it is not made now I would play safe and use 25 to 1 mix.
