Hey folks. I recently acquired a pre-owned Hisun 500, carburated. And surprise... it has issues.
When cold, it typically starts without any issues, but once it warms up it tends to sputter and stall out. When accelerating, you can also feel it hesitating occasionally, and when you stop or put her into reverse, she will often stall. The fuel is clean, I installed a new fuel filter, and the air filter is clean. Though the fuel pump appears to be working ok, it makes a strange knocking sound whenever power is put to it. I've never heard anything like it, and I'm not sure if its shot or just a cheap Chinese pump thing. I have an aftermarket pump coming, and I've ordered a new ignition coil as well on the off chance that it is faulty. I am hoping replacing these two parts will solve the issue, and if it does I will post the results here.
If not, anyone have any other ideas? Also, I've noticed it is very difficult to find parts for this make... any suggestions on a good source for Hisun parts? I appreciate any comments or insights.
