Jeff Great info on all the engines. As you know I have a lycoming in my kr and I am very pleased with the performance and the fuel burn,but it was along road to get to this point. Lycomings are not a bolt on instillation,the carb hangs down very low, the cowl needs to be extended, valve covers have 1/8 inch clearance each side, prop extension is required, swing out mount is a plus, oil cooler required. However I would do it all again.
I believe the O-200 is the best fit for the kr. We are in the process of converting Paul Nunns old kr to a tri gear and putting in a O-200 which seems to be a piece of cake as compared to the lycoming installition. Thanks for the O-200 drawings. The new engine is coming along great I will be taking it down to Doug first week if February. As you know I believe there is no kill like over kill.

I am not going to tell people what engine they hould use, but I will walk through a comparison of the series of Continental nd Lycoming engines that *COULD* be suitable. This is not an endorsement or ecommendation, but only a comparison based on my experience with these engines. WIW, I have overhauled and flown behind every engine listed here with the xception of the Franklin 125. For you Corvair and VW owners, this isn't meant to suggest that they are not iable engines. FWIW, the VWs have proved themselves to be reasonably reliable ith proper care and feeding of the valve train. It is my personal opinion that he Corvairs may still be a viable engine if operated conservatively to reduce rank stresses. While they lack some of the toughness found in "certificated" ngines, it really comes down to ones individual choices for risk management and cceptable risk. "A" series Continentals. If your KR is light, why not use an A series engine? he complaint I hear is that they aren't equipped for starter or alternator. We now the Porkopolis Pig was/is a fine flying plane that appeared all over the ountry and I believe it had an A-65 mounted to it. Build your plane light, and t will fly just fine behind an A-65 Continental. Others have used a Lycoming tyle ring gear on the front of the A series engines and mounted an automotove tarter and alternator. While I haven't done so, I know it can be done. The AE-1 ring gear off the O-235-L2C Lycoming will fit the Continental flange.
