McCulloch Strimmer

GirlRacer_2

Hi guys, hoping someone can help me here. I've got a McCulloch petrol strimmer that I want to use. The fuel I need is 2 stroke and petrol. Is there anywhere I can but it ready mixed or do I need to buy them separate and mix them myself. It all sounds really complicated!

i would guess that the strimmer would need a 40:1 petrol/oil mixture so working on a 5ltrs of petrol you would need 125mls of oil to mix in. After use you can check if the machine is running too rich or to lean by checking the spark plug.

Run engine for a while in normal use. Remove spark plug and check it.

Light biscuit colour = A1 perfect mixture.
White colour = Too lean, increase mixture at carb.
Black colour = Too much oil or too strong a mixture at carb. Also
happens if you only use the engine for short periods.

Also to be really money saving you can replace the 2 stroke for clean cooking oil if you dare. I run a Ryobi this way, and have had many 2 stroke race and road bikes run this way for many years.

That has really confused me now. Normally get a gardener in but thought that I'd have a go myself this year. Can't I just go and buy the stuff ready mixed???

the garden centre will have the oil and you just buy ordinary petrol from the petrol station.
The oil will have the amounts to add written on the bottle.

Sorry if i confused you... i never come across the mixture pre mixed. But all you will need is a 5ltr fuel can (Jerry Can) with normal petrol (unleaded) and a bottle of 2 stoke oil (either from garden centre or petrol station) then add 125mls of the 2 stoke oil to the fuel in the Jerry can, put the lid on the fuel can and shake. Then away you go to fill up the strimmer and the to strim the garden. As culpeper said the oil bottle will have measurements on the side of the bottle to help you. If you add to much oil the worst it will do is smoke a little but wont do long term damage. It really is'nt at all complicted (the hardest part i find is, which to hack down with the strimmer and what can stay).

Thanks you both for your help. This is my job for the Bank Holiday Weekend. I think I've got that. Have always used an electric strimmer but garden so big that I seem to be going thru them annually. Ex hubby had a petrol strimmer which I seemed to have inherited from the divorce but never knew how to use it. Will certainly give it a go.
