Honda 5.5 air compresser will only starg on full

SOURCE: 350 raptor only runs with full choke on ,

Hi Mike,
You will find that there is a problem with the carbie. It runs with the choke on because the choke engages the "enricher" circuit. The idle circuit is different a different circuit inside the carb. When just crack the throttle on, you use the pilot circuit, and then main jet with more twist of the grip. You will need to completely strip the carb, remove all jets, spray carbie cleaner throughout, and blow out all capillary tubes and holes inside the carb with compressed air. Pay particular attention to the fine holes inside the venturi near the butterfly valve. You may need to use a fine piece of wire, like a guitar string to open up any that are clogged.
There is not much else that will cause the symptoms you have. Check for air leaks about the inlet manifold also, spray some carbie cleaner about the manifold connections boots, the revs will change when it sucks up the cleaner through the leak.
Happy to talk to you more about it.
regards robotek

Theres a clogged main jet orifice.. take carb off and check all passages- pass some fishing line through them to clear. Seen this before and THAT is te issue
