I have a Massimo MSU500 UTV and need to check the TPS readings. I think it is the same as a Hisun HS500 UTC. There are not any specs given in the Service manual I have, or owners manual. Any help on throttle body sensor values would be a big help.

It is running very rich. I can only get it started by pulling on the throttle body (clamp loose) and creating a gap at the mainfold on the engine side of the throttle body.
