Ok back at it, was able to remove the old 10 oz tank and replace it with a 14, had a Sullivan so that’s what it got. Yesterday I spent most of the day making a custom mount for a different engine. I’m still not sure I want to run that old enya, probably has the power of a 35 in today’s line up. I flew a Sig Komet for many years with a Super Tigre 75 and this plane is similar in size and weight. I’ll try to set up a possible Super Tigre 61-75-90 replacement and set the original engine off to the side………
