By Hi sun 500
hello everyone, i just joined this forum to try my luck, few days ago i bought an old (dont know exactly), 2011/14 hi sun 500cc ""carburated"", was not running at the time, but i fell was a good deal and decided it to bring it home to play with it, this is the issue, i bought and installed a new carb, and pump, i repositioned the battery location and upgraded to a "car batt", reconnected the fuel lines and started it, but it only runs with the choke ON, i checked the bowl, it does have fuel,but for some reason wont inject it to run, i came across a video that say that ""the body small tank had to be connected for the cart to run" (was deleted when bought), sure enough i got it to run sporadically , but the so called ""small body tank'' often runs out of fuel and wont refill itself , i had to couple times do it manually, so how does that small tank works ?..what does it do?..and why if bypass it , the cart wont start?....any help?..thanks so much!!!

I'm working on a Coleman UTV 400 that has a rough idle, owner has had it for about a year. When I say it has a rough idle, it doesn't have the continuous smooth running sound. At times you can hear it kinda skip, sputter, or like the RPM has fallen (RPM stay constant according to the gauge) It's not as bad as it was after I replaced the fuel filter and fuel injector (both are Chiki) not sure if that is a quality brand at this point. Checked the spark plug, it was a little foul, but not too bad. (Since the engine is still idling bad I'm going to replace that) Cleaned the throttle body making sure the carbon and soot has been removed, and the air-filter has been cleaned. New fuel is being used so it's not old or been standing. They did tell me that they were using non-ethanol fuel, not sure if that would be causing the issue. Next two things I can think of that maybe the issue is the O2 sensor or the valves need adjusting.
Thoughts and suggestions? Thanks in advance.
I have alot of issues with this machine that I'm trying to figure out and fix. Today when I was fixing the shifter I see this cable connection that is not connected to anything. I looked and can't find where it might need to be. Any ideas would be greatfull.
I have a 2012 Massimo MSU 500 that died. I found that it didn't have spark and the fuel pump wouldn't run. Checked all fuses and none were blown.
Went through and replaced the ignition coil, HT lead and spark plug. Still no spark.
Thought it could be the fuse/relay box because I didnt' know much about the machine at that point so I replaced it. No spark.
Then I replaced the ECM just because I was running out of ideas. No spark.
I removed the 9 pin connector and hardwired it making sure that they were no wires got swapped. Still no spark.
Then I replaced the wiring hardness. In doing so, I replaced the 9 pin connector with new ones. I made sure all wires were matched up between the engine harness side and the other harness assembly. Still no spark.
I have no other ideas what to do. My fuel pump doesn't kick on and I have no spark. I have 12V on the fuel pump, ignition coil and fuel injector, but no ground from the ECM control. I unplugged the fuel injector and waited for a diagnostic code but nothing ever came in. It makes me think that the ECM isn't powering up. I've checked for 12V on pins 18 (purple wire) and 15 (white and black wire). I also checked for ground on pin 2 (black wire). All are good.
I am out of options here and I have no idea what else it could be. I have all connections redone and are coated with dielectric grease. I've checked all easy things like fuses and making sure I have 12V in the right placed. I would appreciate any help.
Please help I have a Massimo 400 buck that has an oil leak. The oil is leaking on the front side of the motor. It leaks out of a u-shaped steel pipe that has two banjo style fittings on it. I have tried using RTV and different banjo washers and have had no luck. It drips about one drip per second while it's running. I can't find parts for it at this time.
