Hi, I’m new to the forum. Been trollling here for a few few weeks while I’ve been troubleshooting this 400. Heres what I have. It’s a 1996 Sportsman 400 4X4 2 stroke. Here’s the issue I’m having. It starts right up, idles fine. I give it a little gas and its loading up, at about half throttle it clears up. The carburetor is spitting gas out the back. I’ve rebuilt the carb, new needle and seat, jets. Ive replaced the reeds also. Would a bad crank seal cause this issue? When its running I can see a ton of gas hitting the bottom of the slide. Any info will greatly be appreciated.
