I just checked the choke and it seems to be working properly. Just had it out, drained the battery on it trying to start it cold 4 C. After I heated the engine with a small radiant heater and charged the batt. it started, but there was a strong odor of fuel, so it probably is flooding. At first I tried full choke that is when it flooded I guess, I took the choke off and held the full open and that is when it started. Any ideas
