okay!, I have an 04 ranger 500 4x4 carbed.
it will crank and idle just fine, but won't accelerate or rev . No power at all. cuts out like its running real lean .
I have adjusted the valves, changed the oil, replaced the coil, adjusted the float, cleaned out the exhaust, changed spark plug. ( plug indicates very rich condition) . I have a carb rebuild kit on the way, however , I replaced the carb last year so its fairly new. the fuel pump is putting out 8psi at idle.
anybody have any insight , something else i need to check? Need help fast .... deer season starts next week !!!!

Hi There,

I am having this same problem just wondering if you ever managed to get the issue resolved?

Cheers,

Paul

Mine was doing exactly that and the engine blew up last night!

Could be a fuel problem. Check the fuel pressure before you go to far.

Check the exhaust line on the cam. Although a more common problem on earlier 500's, the cams were made with non hardened steel and would wear down quickly. Especially if they weren't run with 0W-40 oil. Check the rocker arm too.
