Have nice K&B Green head 4 bolt ex./.29 for trade. Looking for good carrier kit. Engine has been test run only on all castor fuel. I was going to use it for old time but have several different engines of same suite. I only have one K&B .29 and don't want to look for another. This is a fine well cared for engine, with excellent compression. Only minor rub on head from old timmer I got it from. Thanks for looking,Dan:+
