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

The clutch engagement on my 2021 cforce 400s was approx 2700 RPM, very abrupt/not smooth. I obtained a "kit" from RNG consisting of a blue painted spring (spring force unknown) with 12 gram weights, as measured on my postal scale. Installation was easy; 18 mm and 30 mm (not 32 mm as seen on other writings) impact sockets for clutch housing removal. The resultant clutch engagement was still up to approx 2500 and very abupt/not smooth.
The original spring was labeled p/n 0951-1021 (specs for spring force 300/1600) with 18 gram weights.
I called RNG who told me the kit should work fine for my ATV, but that wasn't the case as I found.
The RNG spring was slightly longer than the stock spring, but felt slightly easier at initial downward force but had more resistance than stock as I continued to push down. RNG would not tell me what the spring force was.
I then tested the clutch with the RNG spring and the OEM 18 gram weights with the resultant engagement RPM of about 2050 RPM, a little smoother engagement but still not good.
I am really struggling to get any answers on the best combination of spring / weights to achieve a smooth engagement of maybe 1800 RPM. Note; idle RPM is approx. 1600.
I have searched all the forums and cannot find good information, and RNG appears to be not willing to share information. What gives here? Anyone with experience to share?

So I decided to pick up a small trailer if I could get one for the right price. I found this one for a few hundred bucks on Craig’s list. It is a galvanized trailer which is exactly what I was looking for. The wood was shot and needed some minor repairs which I could care less about as long as the chassis was good.
I striped it down and put a new deck on. I had some vinyl realtree graphics that I had laying around so I added them to the fenders which I think worked out well. Very happy with this little guy.
I'm having the iron workers at my jobmake me up a few lightweight side rails that will have a 22 degree bend in them to accommodate the tires that slightly hang over the edge and will incorporate some tie down points as well.
