Small Engines (Lawn Mowers, etc.): McCullough Chain Saw, proper mixture, mixture ratio

Question
I have a Pro Mac 1010 model purchased in the 1970s.  It was last used about 2 years ago and worked well.  I am unable to locate the manual to give me the information on type of gasoline and oil to use and the proper mixture/ratio. Please advise.

Answer
HI KEN


FROM MEMORY 25 :1  FUEL MIX  IS OK  WHICH IS 40 MILS OF  OIL  PER LITRE OF PETROL THAT YOU MIX
             CAUTION  ADD OIL TO CONTAINER 1ST   THEN PETROL THIS HELPS OIL MIX BETTER  

SO MIXING 5 LITRES    USE 200 MILS OF TWO STROKE OIL IN SEPARATE FUEL CONTAINER THE ADD 5 LITRES OF PETROL  THIS GIVES  25 :1  RATIO  

TO HELP  REMEMBER    1000.00  ( 1 LITRE ) DIVIDED BY 25 ( PETROL/ OIL RATIO) = 40

PETROL TO USE  STANDARD UNLEADED WILL BE OK


AS TO MANUAL I AM HAVING TROUBLE MYSELF BUT IF I COME ACROSS A GOOD SITE WITH INFO
I WILL LET YOU KNOW

CHEERS PAUL   HOPE IT HELPS
