The four-wheeler runs fine at the start, if and only if, it's sat for a few days. After riding it for a while it starts backfiring and bogging down when I open up the throttle 100%. It will eventually die and won't even idle without the choke wide-open.
If you are lucky, you might just need new fuel filter and the fuel bowl cleaned out, and maybe new air filter. If not so lucky you need carburetor rebuilt. Backfire is usaully caused by engine running too lean ( too much air for the amount of fuel present). Fuel bowls get gunk in them and the fuel needles and fuel jets get varnished up. The accelerator pump gets worn out gaskets and/or bellows and doesn't give the right amount of fuel mist when you accelerate.
Full Choke is indicative of a motor starved for fuel
