i'm happy with mine. the only issue i can think of is, in certain scenarios, it is hard to start. starting from cold, it will fire on a cpl pulls. after running and i shut it off for 5 mins or so, starts on 1 pull. but if, after running it, i let it sit for 20-30 mins, it doesn't want to start again. takes a cpl of 'purge carb', pull a cpl times, 'purge carb', pull a cpl times sessions to get it to go.
