for some reason my 2000 blaster seems to making some weird noise.at idle throttle it is good and in the high gears it is but in 1-4 gears and in neutral at about 1/4 - 3/4 throttle if i hold it it is like a loud roar noise almost like a 4 stroke or something. i thought maybe the needle was lean so i moved it up. it still does it just now it's a tad more sputtery.?if you give your email adress i can send a clip of almost what it sounds like.also i was running a 250 with my snorkel off and it ran fine, now i put it back on and it seems to lean. oh i'm confused, does anyone elses blaster have this roar noise if you hold the throttle and when you hit the throttle does it take a while to calm down.i never noticed this until i was trying to race and get the holeshot and when i held the throttle it had that funny roaring noise instead of 2 stroke popping. oh i don't know what to do.
