Hi All,
Our Hisun is not making any power. Once you start to climb RPM's it almost sounds like the timing is out, it sputters and farts and doesn't want to climb RPM's at all. It starts fine though.
I checked and set the valves, they were a bit tight but not bad. The spark plug is very black. The exhaust valves are a real nightmare to get to fyi.
On the last service the dealer put the wrong plug in, so I'm switching that back to stock as soon as we get one. I'm also thinking the air filter should be checked/cleaned.
Any other things to check?
