Lots of good choices listed here. Call a few of the more reputable builders and ask questions. You need to be able to trust your engine builder. We are located in Indiana but race in Illinois weekly. If there's anything we can help you with (even if it's just answering your questions), please feel free to call on us.
Our rebuilds are $175 +parts. Not the cheapest, but certainly not the most expensive either.
We have a full line kart shop also featuring clutch and tire work, so one shop can meet all of your karting needs.
25 years full time in this business now -- if we can't help you, there's something wrong.
Any of the ones mentioned will get the job done. I personally run Turner Engines and have been running them for many years. Great service, fast turn around on rebuilds, super power, unquestionable reliability, reasonable pricing, and just an all around good guy to deal with. If I had to pick a second buider it would be JRPW. I have never ran one of Jimmy's motors, but have had a few phone conversations with him, and he always took the time to talk. I think that says a lot about a person.....I wasn't his customer, yet he treated me like one. Good luck with whoever you choose. rick
