my buddy has a polaris 2 stroke that only runs on full choke. I thought maybe a leak between the carb and motor?

have also seen in one or two rare occasions that the "enricher" (what you are calling a choke is not in fact a choke) has been set improperly. I once had a snowmobile and it would not idle or run unless I set the enricher cable so it was on slightly. And this engine and carb are identical to a sled engine, so anything is possible.

I noticed that these engines do not come with a fuel pump, in my experience it is possible to run a snowmobile without on, purely relying on gravity, so in this situation our fuel systems must be clean beyond spotless.
