My first post here as a new member. I have recently bought a 14” 1948 Atco light lawnmower. Having read the user manual I would just like to seek clarification on a couple of points if anyone can help me please.
1. Petrol type - in the manual it says No.1 petrol. Does anyone know if this is leaded or unleaded? I’m guessing that since unleaded didn’t come out until the 80’s it must be by default leaded petrol. In which case should I use unleaded with a lead replacement and does this make any difference for a 2 stroke engine.
2. Petrol oil mix - again in the manual it says to use 2 gallons of petrol to 3/4 pint of oil. This is working out to about 20:1, does this sound about right to others who have the same mower?
3. Oil type - due to the age of the mower all the oil types specified in the manual are now unavailable. I understand from other posts classic oils for classic engines and as such I have bought a millers classic 2 stroke oil that I intend to mix at 20:1. Does anyone have any advise here please, is this the right approach to take?
Thank you for your support,
