Hi I’ve just revived my rc hobby and bought an old kyosho outlaw rampage pro with a os .12cv.
the compression feels a bit low and I’m wondering if any in here can help me out with find parts?
I would like to use the original engine.

If no parts can be found what engine would you recommend for that car?

I wouldn’t bother with finding parts for the old OS. If they can even be found, they’ll cost more than the engine is worth. Quite honestly, I would look for a Novarossi or Picco .12 or .15. Better quality engine, easier to tune, and spare parts are easier to find. As much as I hate to say it, EBay is probably the best place to find parts.

cv12 wasn't a very powerful motor in the first place. If you just have to use the cv12 you might could have it pinched. There's a ton of better motors out there. I'd just pick one. That's probably not the original motor, anyway.

Greetings, Assuming the pressure is awful, isn't the plating worn on the chamber wall? I supplanted the chamber, cylinder associating bar gathering for HPI 3.0G for about $85. I supplanted the course as well as a safety measure.
