I just flew a Scout that a friend bought, up from Colorado today. Great airplane, O-360 constant speed prop. It flew a little slower than my Avid and burned 10.1 g/hr .Costs around 2.5 times what my MK IV would sell for ($80,000+ USD) and I can tell you that I would not trade my plane for it for it even if he kicked in $10,000. The Avid is a lot more fun to fly. The Scout is definitely a great plane and will fit his mission well. I can fly it anytime I want but doubt that I will just because, for me the Avid is just a GREAT little plane and did I mention FUN TO FLY. All engines suck when you are having problems with them and life is good when they are running good. Finish that plane up Allen and come on out and have some fun! i feel for you Jim and have been thinking about your issues, hope you find it soon.
hmmm, didn't do better with carbs from the other engine so is it fair to assume that it is not likely the carbs? I take it that you have checked for leaks in the manifold and crossover. Have you Checked the temperatures of all of the exhaust stacks to see if one is lower than the rest? Man I feel for you been there done that and did not get a shirt to boot
They are available thru Walmart.com aircraft store. Seem like I remember paying about $10 each, for them. I bought two. Same tire but the two I got from Matco didn't last but the Walmart one is doing great. Go figure.
The were several groups of bad floats for the 912/914. Same sorts of symptoms, I fought mine for months finally found the info. The pisser for me was I had rebuilt the carbs including new floats so I didn't suspect them to be bad but they were. There is a SB out on the whole thing. If you can't find it let know and I will look it up. It gives you a couple of ways to check them, including weighing them which is the best way. https://www.rotax-owner.com/en/rotax-blog/item/34-912-914-float-inspection
Jim it is a ETX680C, they cost a lot more but worth it I believe. I put mine in the original position under the baggage compartment Avid MK IV. ONE nice thing about the Lithium iron phosphate is how they work in the cold weather, hit the starter for a couple of seconds then wait five and the battery comes up to full power. Also they hold their charge for months with very little loss. A downside is they take a special charger.
