Since I put an suitable air filter on my 340 (last own had an very slim filter; and air passed free by top and down), fuel consuption has rised considerable. Is there any kit performance or other car replacement for air filter system for volvo ·$= !:/ with solex?

Are you sure that the carb is now adjusted correctly? It really shouldn't make much of a difference. I'd advise against fitting a performance air filter in isolation, as you'll have to adjust the jets on the carb, and it's more trouble that it's worth.

I thought than solex carb hasn't adjust. Could you told me how can I do it? I think that it's ok, but I'm not sure.

The only real thing you can adjust which would make a noticable difference (assuming the carb is in good health) is the idle mixture. I'm not sure how to do that on a B172, but I'm sure someone will chime in.
