There are other possibilities also, suppose the carb could be flooding over…But, it wouldn’t run/idle very well if that was the case… One other thing to consider, how is the recoil rope, is it too short? Is the recoil engaging OK? That recoil is geared down quite a bit, so it takes a good yank to get the flywheel rotating fast enough…If the rope is too short, you won’t get the flywheel rotating very well, even though it seems like you have pulled the rope out far enough… Don’t get me wrong, I am not advising you to yank the rope out real far, and please don’t let go of it letting it snap back, or the spring will probably be damaged.
