MTD brushcutter petrol mix?
I just inherited a mtd pro brushcutter (model bc2??). It has a rounded shaft if that helps. Unfortunately I can't find what 2 stroke petrol mix for the thing should be and no one remembers what it was either. MTD's site seems useless wrt manuals so I'm hoping some MTD owner or somone in the know can tell me what is the typical petrol mix for this brand of brushcutter.

I dont know the model you have but if not sure of the mix go 25/1. If this smokes all the time when running then try a bit less oil next fill.

Seems like one of the relatives wrote it down in a book and seems to be 40:1 or (5L fuel: 125ml oil). How accurate that is is anyones guess.
For anyone reading this please do not take that as gosple and if you damage you mtd brushcutter it's your issue. I take no responsibility or liability.
Personally I don't really care since it's hard to start and various covers have fallen off and it has a crappy head on it so if it dies I'm not too worried. Last thing I want to do is run it too rich and have oil coming out of the exhaust and inhaling it for a hour or two. Done that in the past. I'll take the chance given the conditions.

The American site seems to recommend berween 32 to 40 to 1 mix depending on year. You may download a manual on the second link. These ratios have a lot to do with emissions - I have noticed that some machines operate a bit hotter on such ratios - don't know why -maybe not enough oil in the mix - possibly the makers are trading off the longevity of the machine to satisfy emmissions laws??

Most brush cutters, well those that I have had and killed seem to like 40:1 or 50:1, the current little Ryobi el cheapo thing uses the 50:1 mix.

Thanks everyone. That support site and the chimes of 40:1 or 50:1 give me much more confidence that the 40:1 recommendation a relative passed on was probably right for the unit I have..
Cheers!
