1993 Trail boss 350L 2 stroke boggs down after 200 yards running normal

[andyt]

I have a 1993 Polaris Trail Boss 350L 2- stroke.  after about 200 yards or so of driving the motor boggs down.....it will stay idling but if I floor it, it will die.....if I turn it off and wait a few minutes I can turn it back on and go like hell for another  couple hundred yards.... I thought the pilot might be worn out(I have it nearly closed now)......maybe the choke plunger isn't sealing or the Bowl isn't filling quick enough.....any suggestions would be appreciated.

Were you able to solve this? Is the carb clean/choke working correctly? Maybe a bad coil?

Crazy......reserve screen in take was a little dirty and the straw for the tank was up high enough it wasn't getting gas from there.....inconsistent flow from the tank

Oh wow, nice find/fix.

Had the same issue years ago with a 250 2stroke trailboss.  It turned out to the gas tank vent hose.  When it warmed up the hose would collapse shut.  A quick way to check is by opening the gas cap a little and taking it for a ride.  You only need the cap open just a little to allow the tank to vent.
