Are these ports connected to one another? They look like they ought to be but I get no flow between them, even after about 3 hours in the ultrasonic.

Yes, that is the port/orifice the choke enrichment circuit draws from.

It must be open for the fuel portion of the enrichment to function.

Thanks Randy - back into the cleaner with 'em

Try using carb cleaner but first use fine sand paper to "sharpen" the red plastic straw into a fine point.  That way you can push the point into the very small openings and pressurize them to blow out the crap.
PS..wear safety glasses as carb cleaner hurts when you get it into your eyes!  DAHIK.
PPS.. what are our friends in California gonna do now that plastic straws are illegal???? :wacko1:

Well I'll be damned, sounds like this happened to someone else...
Isn't it remarkable how you spray the cleaner into the opening at the gasket line, only to have a thin stream of cleaner come right back at you and hit you in the eye?  From a tiny opening at the bottom of the fuel bowl to right smack dab into your eye?

Fucking amazing if you ask me....

Carb cleaner is on the shit list around here at the moment. Fume's get sucked back into the house and the wife is less than impressed. Strangely, I can't smell it at all.
Used a very small drill bit to open up the passage and then back into the tank with 'em.
Fucking amazing if you ask me....

Wow, how many times have I posted about this choke fuel orifice?
