I agree the MECOA 46 is a good starting and running engine. I have two in a Wing P-38 that goes like a scalded cat. BUT!!! I ordered carb parts 10 weeks ago and got one replay that they are in the process of moving. That was 10 weeks ago. After that, not a single reply to NUMEROUS e-mails and they never answer the phone. Good engine. Very lousy support. Never again. No more MECOA for me. If I don't hear from them soon, I'll get two new OS 46s . Their support is fabulous. Always has been. Swifter
