I bought an old Fox mini, and it came with an Hs40, and (what I think is) an old HS35 or HS40. I haven't found any numbers yet. The 35 has a lighting coil, but no flywheel and no compression. The HS40 is good (I think). The carb is pretty nasty. I was thinking of rebuilding it, but $20 for a new carb is pretty tempting. I've got an new carb off of a 212 pred. Can I make that work if I whip up an adapter? Will that be too much carb? I'm not going for a restore. I just want it to run. Any input is welcomed. I'm also not afraid to rebuild if you think the old carb is worth it. Im pretty excited to start this.
