What year quad do you have?
I think you have way to rich of a Pilot Jet because 50 Pilot in Dynojet brand is bigger then normal Kiehin jets. One trick to try is turn the Choke ON, now if that was a Success then you're Pilot jet is way to rich.
Dynojet 175 is equal to a 197 Keihin (OEM Jet)
Dynojet 50 is equal to a 57 Keihin (OEM Jet)
go with oem jets or at least use a Jetting Size Converter because Dynojets cause a lot of confusion.
If you clean the carb Dissemble the entire carburetor, take all jets and mixture needle out being sure not to loose the springs that go under the mixture needle aand so on, use compressed air (don't use carb cleaner if you have a FCR Carb)
