My quad keeps stauling on me i think its cause it could be flooding,,need to fix this problem asap

Most likely the engine cylinder head gasket has blown causing oil and coolant to flood the engine and cause smoke. This will prevent engine from starting. Looks like a big job ahead to fix. Try not to keep cranking the engine as the pistons could seize inside the engine cylinders. I hope it is not as serious as I may have made out to be. Please tow the car to mechanic asap.

1. fuel pump to strong.
2. needle seat blocked.
3. wrong carb jetting

this is possible faults

You need to run a compression test on the cylinder to see if a valve is bad

it could be misfiring, where did you get those codes? but the Crankshaft Position Sensor should be somewhere between the intake manifold and the firewall. The Quad Drive is electronics related, supposedly the most common cause of this code is the EGR valve (exhaust gas recirculation) and should be near the cylinder heads and are also said to be easy to replace. Quad Driver A module monitors the low speed fan, Evap canister purge solonoid, the HIGH TEMP light, and TCC apply. Quad Driver B module covers the shift solonoids and EGR valve.

replace the needle and seat in the carb

If it started yesterday you might have fouled the spark plug or check crank case, air intake system, and exaust pipe for dirt dobber nests if both have sat up for some time I had this problem when I bought one of the same 4wheelers what happens is the crank case builds pressure also the exaust builds pressure and will not let the motor run check for ignition spark parts are vary cheap for the pocket minies check ebay i got a exaust pipe for 13 dollers 49cc also check motosports max.com or type Kazuma.com in your search bar

Replace the auto petcock it's cheap rubber and degrades pretty fast.

some times its better to get new forks, as they can be stressed when straightening them, you dont need them snapping off while your riding

faulty idle speed control.fuel filter can be clogged.bad spark plugs and wires.intake gasket leak .vacuum leak at hoses.also scan it coolant temperature sensor and egr valve will cause stalling problems.

Sounds like fuel pump
