RE: K&B Engine Identification?
Fitz:
What you have is the K&B "Sportster 65" engine. And if the carb is tight in its mount there's nothing missing - it uses a clamping bolt. If it's loose you might be able to figure it out looking at the parts diagram on the MECoA site.
This engine is an excellent torquer, it does not like high rpm. Keep it below 12K or so, and with castor oil lube it will last a long time.Use a low nitro fuel, any more than 10-15% is wasted. Also, don't be worried by its mechanical clatter, all the "Sportsters" are noisy.
Yours is next to the latest production version, differing only in not having a remote needle from the current engines.

PS: No fooling about the castor oil. This engine has a plain bearing crank, synthetics just wont do it. A blend, like Omega or Powermaster is OK. If you can only get all synthetic, add four ounces of castor oil to each gallon. wr.
