Good carburettor. Which one should I choose?

[CharlieWex]

Which firm can you advise me on in this matter?

[KerryBolt]

I don't understand anything about it. I think you need to see a specialist, but I don't know.

It depends on what you need it for. Personally, I use it for different situations. Read the ryobi 2079r manual and you will get a lot clearer, at least you will understand what you need.
