I think that we got a dud as the other one runs great!
Mine ran for 40 minutes of an 8ozI have five of the Evolution 10cc engines with pumped carb best darn little IC engines made, the non pumped if you set up the tank right and checked the O ring under the carb would run very well also. 8 ounce tank you will get tired of flying before you run out of gas. Using Amsoil Saber I have been running mine at 50-1 going on 2 years now and they handle it well and less cleanup. Big difference is power as running less oil thru this small carb and more gas gives a some extra zing.
I love the look of that motor! It makes me really want a gas plane...I only wanted to do this once, so I'm doing it right and making a template. I've verified that I'll still have access to the muffler bolts, which is good because the muffler blocks access to the engine mount bolts on the right side of the engine. Space will be tight, but a fuel filter should fit inside here as well. Throttle access will be good, and I carved the left cheek a bit to make room for the high needle adjustment. I also went a little old-school with that needle and stuck a small hex wrench in there for easy access.

Measure three to eight times, cut two or three, sand a bit, with multiple test-fitting inbetween each step. Add glue, and wait! Once dry I can do some final sanding & shaping so it'll be ready for covering.

How are you going to run your ignition cable and box and are you adding an Opto switch? Me personally never use a gasser with out one.
You can ground the magneto with an rated opto, just need to run the ground wire through it and think backwards. Open is run, closed is off.
