My cforce 600 don't start. I do not know what to do.

-the starter works well
-the spark on the plug is ok.
-the fuel pump is ok
-the injector works with a nice jet
-the air filter looks good.

What is the next step


Thanks for any help.

Compression check.

Yep and then check the valve timing. We assume the engine is turning over with the starter and that it has air,fuel and spark so it has to be a compression or a valve timing issue.

The atv is practically new. It worked very well when I parked it but when I wanted to use it!!! Nothing.

I will check the compression.

Thanks

Even new engines can jump timing. If it did, compression should be low.

Take the valve cover off and inspect the casting to make sure nothing has broken (we've seen this happen), and check the timing marks and chain as well.

If it's under warranty don't do anything, take it to your dealer's service center.
