I’m getting a 700-7 every startup. I’m having to change the plug every 100 miles on 93 octane gas. I got a lower numbered plug that is supposed to burn hotter. I’m wondering why that comes up every time I start it and if it’s related? I included a picture of the code or whatever it is. I haven’t seen the code in the owners manual or the hisun shop manual I have.
Hopefully this helps somebody because I couldn't find any info on this runaway condition.
Drove 1/2 mile to the gas station and when I started up to leave the starter stuck on. Turn key off starter is still running~! Limp it home wondering what the heck to do, get it in the garage and pull the negative battery terminal to get it to stop. Whew, WTF?
Calm down and start checking things, starter is hot of course but nothing is smoking and nothing smells burnt. Pull battery cover off and start checking wires from battery to relay and relay to the starter. OK good nothing is hot, nothing is crispy and nothing is melted. Probably smoked the starter though. If this had happened to my wife and I wasn't around the machine would have run until the battery died and probably melted down/burned.
I'll get to the point to save you folks some time and trouble. Because this is a kymco machine you need 2 different Kawasaki parts to make this repair, and information is scarce to say the least. The switch and a sub harness to connect it to the machine's plug.
Everything works now, but the starter sounds horrible so I'll be changing that too before spring.
Good luck out there and hopefully this is just a freak occurrence, but if I were you I'd get rid of this kymco part and put the Kawasaki replacement in now.
Switch, Magnetic is part number 27010-0767
Sub Harness Start Relay is part number 26031-Y034
I have a Coleman 550 (hisun). Wouldnt start and was sucking instead of blowing through the spark plug hole. Got to the timing chain and it was very loose and for sure the timing was way off. Got the tensioner off and set it to TDC and got the cam gear back aligned. Put the chain back on and set the tensioner as instructed and the chain is still very loose. I extended the tensioner as far as it would go to test and the chain is still loose.
Any ideas what could be broken or wrong? Why would the chain be so loose?
