word, you put something in perspective for me. 53,000 km on your agility. Not sure why I got so obsessed about carb cleaning, hell, I just turned 2800 km today. Thats 1800 mi, the engine likely is not even fully broken in yet! Could these quirky start up problems be related to that? Now I recall many of the cold start ppl 50 issues were those with low mileage engines.
