Yea i hear that. It  was the way the pwk was wont run either way.I cleaned the filter on it tonight.I got looking at the plug down at the bottom has alot of color on it, for the short time i ran it.I m going to order some jets Monday for it.Its hard for me to get jets unless i get them off the internet. But it did run better tonight on the 240 then it did.It pulled harder in the topend this time.But its like im running out of gear. All i can do is mess with like you said. If i can get it to run like the bottom and mid its going to be mean for a 250.
