As it should be easy to see I am not a four wheeler mechanic so I apologize for asking for help, I replaced my OEM carburetor with a aftermarket carburetor and with y’all’s help adjusted the air/ fuel and it ran great until this evening and I noticed a smell of fuel I inspected carburetor area and found a steady flow at the vent line on the bottom of the carburetor so my question is is the float the only thing that will cause this problem? Before I installed the carburetor I checked the jets for tightness and they all seemed fine?
How much it worth?
Pros: looking decent.
Front wheel bearings are shot.
Idles, but sometimes will shot off. Most likely when cold.
Gas smell and little bit steam in the air filter box when I started it.
Display screen won't work.
Tires are dry with cracks.
Not sure if has title, I will check and update.
How much do you think it worth?
So, I found myself in the only 5' deep water hole in Moab with the King Quad. Before I could get off it swallowed water at idle and died. The river water was not very clean. I pulled the plug and pumped the water out of it with the starter. I cranked on it and it popped for a second and then was done. Towed it back to the trailer. When I got home I checked the compression and it had none. I have a factory service manual. Disassembled and found the rings stuck in the piston lands. New rings and back together. I try to start it and get a C12 code CKP - crank position sensor. Troubleshoot and find it to be shorted. Installed aftermarket CKP, still get code. Check voltage on new CKP and only get 4.5V, manual calls for 5V minimum. Pulled every connector apart on vehicle and cleaned. Have continuity from CKP sensor side of connector to ECM harness. Install a known good ECM from another 2005 KQ I have. Vehicle fires and I let it run for 10 minutes. Shut it down and put the original ECM in and get a C12 code again and won't fire. Put the known good ECM back in and get C12 and no fire. Tested both ECM's in the other KQ and runs well on both ECM's. Installed a used stator and CKP. Still get a C12 code. Check used stator, 200 ohms and 6.5 V out of the CKP at the ECM harness. Checked ground at ECM harness and it is good. Checked spark with spark plug and without, none. Checked resistance and peak voltage on coil and it is in spec.
This thing has me baffled. All of the electrical possibilities seem to check out. Might be far fetched, but could the rotor key have sheared when it shut down suddenly when the cylinder filled with water? I know rotary lawn mowers can shear the flywheel key when the blade stops suddenly from a rock or stump. If the key is sheared and the flywheel is out of time by a few degrees could this be giving the C12 code? The voltage output is correct but at the wrong crankshaft position (wrong time).

Just bought 07 450ER and took it out for a ride(20 min) came back in and saw oil on swing arm. Upon further inspection found it was coming from air box. Wondering if it could be to much oil ( draining and refilling both tomorrow) , or possibly something worse. Guy isn't answering any questions now smh.. thanks ahead of time
