Don't think u can adjust the throttle position sensor check ur throttle plate in throttle body make sure it's not gumed up with carbon, try idle screw and u could have a bad o2 sensor in front of cat converter

did you say your fuel pressure is 50# ? drop it to 35# and see if that fixes your richness.

i went to 40# it helped. i'll try that.

      2010 Hisun 500 - Carbed'.  She sat for about 3 weeks since last use.  Couldn't get it started.... has spark but plug was not wet.  Bought new plug, cleaned the carb, confirmed fuel pump (pulse type) is working.  Still nothing.  Put gas in the plug hole.... started right up and idled as normal and drove perfect.  Used it for the rest of the day without issue.  Tried to start again next morning.... same problem.  Poured gas in plug hole again.... started up and best kind again.
      Anyone have any insight to what's going on?

      I'm looking to purchase a 2015 Massimo 550 that might have an issue with it's throttle position sensor.   
      From the fella selling this UTV, he claims its to set the idle on fuel injection because the engine will not stay idle or when it starts sometimes it idles too high.
      My Question if anyone had any issues with their Massimo 550 and if it was actually the TPS or something else that would allow the machine to idle correctly.
      Thanks!

      hi everyone i have this 2021 Hisun forge 250 that won't start. no spark no fuel.   when i turn the key on i dont hear the relays click or fuel pump come on. it does have power but the relay doesnt ground the pump or the ignition coil. dont know if there are any safety switches on this model or not.  it does crank and all the accessories work. i  hot wired the pump and it does work.  i found a wiring diagram but it's very hard to figure out and was hoping someone has seen this before. all fuses are good. thanks in advance.

      spits fuel from breather hose into the air cleaner and then down into carb.  What’s causing this ??

      Hello, I have a 2013 500 utv hisun. Was running ok and cut out while parked. Bike will not start now. It turns over, but won't fire. I have no spark and no fuel. I replaced fuel pump, ignition coil, spark plug, cdi, voltage rectifier and all the fuses and relays. Could bad stater cause no fuel because I can't hear the fuel pump priming. Any info on where to start looking for problem.
