Well all I will tell you is that ATV COMES with a D8RTC china plug it says right in the manual look for yourself. Where do you think I got that the C7HSA is the wrong plug I did not pull this out of my ass. MAYBE THE SERVICE MANUAL FOR THAT ATV IS WRONG.
I did mention it way back about the plug being the wrong one. It actually happened with some 50cc scoots that a dealer could not get the motors to start. It was on one of the 3 forums, I mentioned it as a possibility and the dealer checked and took the head off one and sure enough the plug was not protruding into the chamber it was firing but inside the head. He got a hold of the manufacturer and they sent him out new heads.
But in your case the manual says that motor takes a D8RTC the chinese scoots always come with their torch plugs. The dealer you got the harness I would bet he does not know much about your motor and just grabbed the most commom plug for your gy6 and clone motors which are c7hsa plugs.
The D8RTC has a thread diameter of 12mm
Thread reach of 19mm
The NGK DR8EA has a thread diameter of 12mm
Thread reach of 19mm
The C7HSA has a thread diameter of 12mm
Thread reach of 12mm
So what is not fitting?? did you get maybe a NONE NGK PLUG DR8EA?
Because all are the same Thread Diameter just that the DR8EA is longer.
I don't believe all the cross reference charts from all the publishing I checked to make sure are wrong.

Ok i BELIEVE I found your problem you have the wrong plug the C7HSA has a thread reach of 12.07(1/2 inch) and the one you need is NGK DR8EA which has a reach of 19mm(3/4 inch). So I believe I was right the plug is firing but not in the chamber it is firing and grounding out on the threads of the head in other words the C8HSA is to short of a plug.

Well it could have great suction but if no gas is being sucked out then no fire Or if to much gas then it floods the spark out and no fire either. If the motor was not taken apart and you have great compression and the spark plug sparks on the motor then it is a Fuel problem either no fuel or to much fuel. So lets re-check that, put the carb back on have the choke OFF down. and crank it NOW take the plug out and see if it is WET OR DRY. 1. If Wet and it did not fire once then the PLUG IS NOT FIRING while screwed in. Are you sure you have the right plug meaning in LENGTH if to short it will not reach into the chamber and ground out on the side of the head on the threaded part. 2. If Dry and it did not fire once then NO GAS IS BEING SUCKED into the intake. What happened here? |

Testing thiings just using the kickstarter is crapoola it is not good enough, does not spin the turn the crank enough to produce much of anything. Start the the motor then test the wires from the stator. Also what colors are the stator wires that plug into the R/R? Not the two wires that go to the CDI(which one is the pickup coil wire and the other is the CDI power wire).

30Vac with motor not running is fine, if your testing the stator output start it and rev it up to about 4k and it should read 50+vac. if so your stator is fine . If it is not charging your battery and the lights are dim 99% of the time its your Regulator/Rectifier that went south.

Question when the choke arm is down what is that INSIDE that appears to be blocking use from seeing all the way through to the other side ?

Where that pin was looks like it goes to the carb bowl May its a vent for it. How about the CHOKE ARM did you look inside and see what it looks like when you move the choke arm.
I have to tell you I have never seen a motor like that one.

On that Carb to adjust for more or less fuel you adjust the AIR RATIO screw. Turning that screw CLOCKWISE CUTS AIR and ALLOWS more fuel, COUNTER CLOCKWISE ALLOWS for air to FUEL ratio.
That carb sure looks lit it is for a 2 STROKE which requires oil mixed in with the gas. Are you sure your motor is a 4 stroke and or that the carb was NOT changed? Picture of the front of the motor will verify whether it's a 2 stroker or 4 stroker. I need to be sure what I am dealing with.

Ok good shots of the carb, So it has a AIR RATIO SCREW the screw near the Air Filter the middle one is the IDLE SPEED screw.
Also that HANDLE on the other side is THE CHOKE Since you have it off MOve that and see in what POSITION it closes the INTAKE and which POSITION it lets air in. Since the plug is carboned up I would bet the CHOKE is on butterfly is blocking the air from coming in.
So put the carb back on and clean the plug and do not choke it and see if it acts better. If it appear not enough fuel close the choke SOME NOT ALL THE WAY and see if that helps.
