I had another great day with the Sukhoi today and realized the Webra 120 is the best engine I have ever owned. I would guess it has 10 gallons through it. Still on original plug and propeller. Never flamed out on countless flights. It easily hand starts, idles superbly, makes decent power, and is easy on the fuel. It may not have the mot aesthetically pleasing sound, but it hauls the 'koi around with perfect predictability.

A truly great engine.

Now! Now! ilikeplanes. You probably adjust it properly and generally treat it well. How will it do adjusted a 1/4 turn too lean and sand being sprinkled in the carb at the same time. That's the standard to be used.
