Hey Artisan,
The guy was worried he would have to fuss with tweaking his engine all day if he got a 4stroke. I said I don't fuss a lot with mine. I didn't say I have someone else tune them. As a matter of fact no one tunes my engines but me and I am the field 4-stroke 'expert'. My engines don't require a lot of tuning and work fine for me. I shake my head at the guys that think they have to reset all of the needles every time they fire up an engine. I would if I was trying for a speed record or something but for just having nice flying 95% of perfect is plenty. I spent 30 years as an engineering analyst developing advanced propulsion systems and know something about tweaking things that need it.
