Here is a pic of the Roto35 running. After getting it started I had no problem tuning it. Compared to a nitro engine the tunig adjustments are quicker. Maybe 5-10 seconds after an input to the high or low needles. Because I have a long fuel lead, I have an extended time of primiming, so I'll just use a starter until she breaks in, or I find another solution.
