Rhino 700 running rough
Hi, I am working on a friends 2009 Rhino 700 which is difficult to start and when it is running seems to be missing and maybe backfiring at high revs. Seems to idle ok. The history is that it started running rough and misfiring then started being hard to turn over - starter motor just clicks but doesn't crank over and wouldn't start at all. Found the starter motor and solenoid were defective and replaced both. Now it will crank over, but only if I jump start directly onto starter, so I guess I have bad connections somewhere. All connections seem ok, but any ideas would be appreciated. When it does start, it idles ok and all of the sensors appear normal, but when revved it gets a crackle and hesitation at high revs and seems to have a bit of a backfire. I did find some of the wiring harness had been chewed by rats, but have replaced those wires. Checked timing, coil, fuel pump pressure, all of the FI sensors and all seem ok. Tried new spark plug, no difference. Anyone have any ideas?
