Put a new carb on the 500 to replace the leaking OE one.  Machine idles fine and mid and top end runs great.  It tends to have a hesitation right from the start - bottom end.   Thinking it may be the air/fuel screw??  I didn't do anything with the carb out of the box and is it direct replacement for my machine.  Of interest is the manual choke doesn't seem to work very good now.... wonder is it getting too much air?

 

Any help appreciated!

Just going to follow-up on this one.  I turned the fuel/air screw out 1/4 a turn (counterclockwise) and the hesitation is all but gone.  Might do another 1/4 turn rid it completely.  She needed more fuel.

It sounds to me that the acceleration nozzle (or pump) needs to be adjusted. 

The thing runs great at idle and mid and top range. It only needs more fuel when you open the throttle.

      2017 Massimo MSU 500 top end kit
      By Jerrys500
      Hi I'm about to order parts to do a bunch of work on my Massimo. Does anyone know if there's a difference in the top end kit {piston, Cylinder, Rings, Gaskets, Piston Pin} if it has a carb or EFI? I'm EFI and I think some came with a carb so I thought i'd ask before making a mistake...
      Thanks Jerr

      2020 Axis 500 - only getting reverse and neutral
      By JimG
      Recently, my unit Axis 500 (2020) will only go into reverse and neutral. I am not able to get high or low. The engine itself sounds fine and I do not have other issues on this unit. I change the engine oil but have not yet changed the gear oil.
      Before this happened I occasionally encountered issue where going from reverse to high gear, it would grind some and i had to reposition to shift into high gear. I also for last couple weeks heard a squeaking sound. I couldn't tell what it was. Was looking for a grease point I missed.
      The unit has around 70 hours and is kept in the garage.
      Anyone else encounter this type of scenario? Any suggestions on troubleshooting would be appreciated. Thanks.

      2019 750 Challenger won't start...
      By JDawg
      Was using the machine all day to haul wood...no issues until the end...
      When I try to start it, the dash lights come on but starter does not...seems like no power to the starter.
      It is in park, but when I put the brake on to start, it registers N.
      Won't start in neutral either...
      Tried rocking it, did not help...
      Help...

      2013 hisun 500 efi utv. No fuel, no spark
      By Robby
      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.
