Changing the derailleur is only due to the fact mine is not capable of moving to 34T (at least that's what they say in the specs).
I run :
- Sora rd3400 rated up to 27T
- Sora SS r3000 rated for 32T Max
- Altus M310 rated for 34T Max
they all run well with 34/36 sprockets. the r3000 and m310 run 40T without problem too.
your tourney (most likely a RD-FT35-SS) is rate for 28 max so I would expect it to work with 34 or 36 however, you would nee to adjust the b screw.
The big unknown is the 24 to 34 jump hence my suggestion of the IRD Cyclone 7 Speed Freewheel - Shimano Compatible
13-32T: 13 / 15 / 17 / 21 / 24 / 28 / 32
the 28 to 32 jump is normal and the rest of the gap is much better.
