I bought the sled last winter and it Boggs down when you hit full Throttle doesn’t matter how fast you are going it Boggs until I let off.
every time I drive for awhile hour ish and unload the sled it is extremely hard to start end up just putting gas into the carbs to get running
If anyone has and help I’d much appreciate it thanks

ck compression first , if compression is125 ea min 110 , put new plugs in , pull the carbs and clean, make sure u use a wire to clean the jets ,check the choke plungers while apart, ,also look at the reeds when carbs r off , they can cause hard start and performance issues

Check clutches for wear too. If they aren't shifting properly it's going to bog.
