Default Reliable, quick nitro motor for RS4?

I am looking to put a new motor into my Nitro RS4 2 because my .15 FE lost compression. I don't plan on racing it at the moment but I would like it to be somewhat quick. What motor is reliable, fairly quick, and well priced that would fit in the Nitro RS4 2? I would like a motor that I do not have to cut the shaft on and that would use the stock clutch assembly with no modifications. Pull start is a definite necessity. I would consider a slide carb... I really appreciate any help you guys can offer.

Thanks in advance!

check out an O.S. CV-R .12. Fast and around 130 bucks for a oull start of www.towerhobbies.com

These are super easy to tune, and you can get it in almost any config. you want.

25mm from the inside of each bearing.

What do you mean by horizontally? What measurement exactly?

Like sushi boy said get the cvrx("x" means pull start). The os cv-rx is all the power and speed you need. If you want something cheap and with a pullstarter. Go with that engine. I hate pull starters. Id never put one on my car unless the engien was free. But hey, thats just me. Slide carb are mostly found on engine without a pull starter. No matter what engine you get, how it performs depends on tuning and takeing car of it. The stock fe is a great little engine. i'll miss mine
