Got the KDX220 out for the first time this season. Put in the clean air filter, and some fresh gas, and it fired right up on the third kick. I was impressed! It took it a while to really warm up and pull hard though. Put she is right on now, took it out along with my buddy to a new area we found. Running like a top. Well, the top didn't seem to pull too hard, maybe its just me. Is there an easy way to check the powervalve, so make sure its working ok? Thanks.
