How critical is the oil/petrol ratio for a 2 stroke engine?
(Jon Weaver) wrote in message . com...
I have a McCulloch strimmer which takes a 40:1 petrol/oil mix.
However, my mixing bottle (which takes 1 litre of petrol and has a
pointed top graduated in different radios) has become 'bloated'
This means that when you fill it to the 1L mark, there is actually
more than 1L in the bottle.
If I then top it up to the 40:1 with oil, I am getting a slightly lean
mix.......
John..When I bought My Mcmulloch strimmer two years ago the
instructions said 40:1 when using McMulluch oil but 25-1 when using
anything else.And this is what I use..25-1...which is the same as my
previous strimmer, a Ryobi.I use it most days at work.No probs.My
mixing can is 5 gallons and the oil I buy is the normal sort from
Focus or B and Q and ratio measures on the side. Post later or email
by which time I shall have found the original instructions...Ken
