I picked up this ATV that had no spark. The previous owner said he was driving it and it died and would not start. He discovered it had no spark. He replaced the CDI and the coil with no luck. He got tired of it and I bought it. I replaced the stater and now it has strong spark. Now, it starts for a second or two then dies. It will not stay running. I have checked the timing and it is spot on. The valves are adjusted correctly. I see no warn issues with the cam. I put the original CDI and coil back on it. Same problem exists. Compression is at 65 psi (has decompression mechanism),
I took off the muffler in case the issue was clogged pipes. No change. I replaced the spark plug. No change. The carb was an aftermarket so I put a Niche carb on with no change. I bypassed the fuel pump and that did nothing to solve the problem.
I don't know if this is a carb issue or an ignition issue. I am looking around locally for an OEM carb to try out but not sure that will fix the problem.
Can anyone help me solve this problem. I am running out of ideas.
Thank you for your time

Hi All. I introduced myself some weeks ago with my 2006 LT-F400F that needed a list of repairs including replacing the cracked generator cover. It is back together as of last night and cranks up, idles and revs high pretty well. Needs some fine tuning and stop backfiring at stop.
The big issue is it will not go into gear. I reassembled the insides with help from y’all’s posts. The transfer selector moves from H-L-R, and the foot shifter moves thru the gears and finds neutral easily enough. Before I tear it back open, the transfer selector on top does not move as far as the repair manual says. The diagram shows the shaft moving something like 40 degrees between L and H and 50+ degrees between L and R but it doesn’t move that far even though it finds the indent areas and moves well.
Could this be the problem. I aligned all the dots on the shifter gears inside and it appeared to not be binding anywhere. I do hear the gears touching when I shift like they are trying to engage, but zero movement from the ARV
It was somewhat difficult to tell whether all the parts are installed on each shaft.
Are there better/bigger photos somewhere that would allow me to be confident I included all the washers and bushings, etc? If I had any doubt on parts that were laying inside after the cover broke then I purchased replacements from online stores.
TIA for any input or feedback!! Pics are from when I first took the generator cover off.

My son's trying to get a 2003 Prairie 360 running. Over a year ago, he'd rebuilt the carburetor using a SHINDY 03-112 rebuild kit from JT Cycle & ATV, and it was working fine; however, when it wouldn't run recently, he took the carb apart and the jet needle was rusted in place. He cleaned that up as good as possible and replaced the jet needle with the old one that wasn't rusty. Now, he can only get it to start about 1 out of 5 tries, and when it does start, it won't run unless the choke's on. The spark plug's good and is sparking. It has compression. Any ideas on what he should try next or look into?
