I had my trailer loaded up with woods last night, almost enough to get the front wheels off the ground when steering... Well, I decided to drive through what was left of a snow bank... I got the back tires spinning a little, and the motor lugged right down so low that I could count the times the cylinder fired... It sounded just like a John Deere "D" pulling!!! CHUG! CHUG! CHUG! CHUG! It didn't stall, and kept pulling. I am sooooo happy with how the motor is running! With choke on notch one, two cranks and she fires right up! I couldn't be happier!
