Default RE: Quadra 75 replacement gasser

I'm surprised you would want to replace the 75. That is a great but old engine that I doubt you could ever wear out. Its rear exhaust is good for warbirds and though it has a side carb, it is tucked close to the case. It fits well in most any cowl. Mag ignition not your cup of tea? No problem as it adapts easily to electronic ignition. The 75 isn't the smoothest running engine from a vibration standpoint but it is on par with the DA-85. Yes, the 85 will be more powerful and it will be shiney and new ... but better, I wonder. Sorry if I didn't answer your question but I am a 75 fanboy.
