I don't know the proportions of mixer to petrol for a leaf blower

I am using a friends McCulloch Blower Vacuum 243 whilst he is on holiday, but have used all his pre-mixed solution. I don't know what the proportion of mixer oil to petrol is. The mixer bottle states fill with petrol to 20:1, 25:1, 40:1 level - which is the correct level for the 243?
Can someone help me please.

You are not going to hurt the unit if you run a 20:1 ratio on the unit until your friend gets ahold of you and then lets you know the proper ratio. when I use mine I do a 20:1 ratio and sometimes I just guess and have had the same blower for over 6 years now. McCulloch is apart of husqvarna and ushally theirs are a 20:1 ratio as well on the smaller units. bigger the unit ushally the bigger the ratio.

As I've lost Operating manual for this Blower, could you advise if it is a "2/stroke" mixture, i.e. what petrol/oil mix is required


If its a hand held Vac/Blower then I don't know of any that aren't 2 stroke.

Your part number isn't much help, you're welcome to post a picture of it. As I say, if its handheld and petrol then it will be a 2 stroke. Mix ratio is generally 50:1 That's 100ml of oil in 5L of petrol. Some manufacturers use a ratio of 40:1 which if used in the wrong machine can seize the engine, doing more damage, so stick to the 50:1 ratio to be on the safe side.

Ryobi blower stalls


Not sure if your model has two throttles or one. It should have a trigger and a thumb lever. Be sure the thumb lever is closed. if that is not the problem your mixer might be to rich. it says 50:1, but use 40:1 and see if that helps

The engine revs high then low.


There is a way to remove fuel filter although I don't know if you can clean you might have to replace it. Other reasons for high and low revving could be that the carb might be adjusted correctly.
