Where is the pilot jet? If it's accessed through the top of the carb, I cannot, for the life of me, get the screws undone to remove it. The float bowl screws are security type, with breakaway heads, so that's a no go also.
FWIW, I was talking about it with my uncle, and he said it sounds like a choke circuit problem. There is evidence of the choke solenoid being monkeyed with - the hold down bracket is bent and one screw was half out.

Oh please post a picture of this unit. Security screws in the float bowl? Interesting.

Yeah, the original carb in my '20 Tao Tao had them.

My assumption is that for reasons of emissions tampering they did that? Perhaps they could have had too many warranty claims from TinkerBoys?

Top cap screws will not budge. I'm afraid I'll strip them. Security heads on float bowl (well, one of them, at least). 5 Wonky choke bracket.

The retainer clips for the auto choke do seem to have a slight bend to them, normally, mostly at the ends, the ears with the screw holes. They seem to press the choke down a little into the hole. At least the few that I have messed with all seem to have slight bends in them. The screw obviously should not be coming off, so someone def had to have done that for whatever reason.

My electric choke has a plastic base ‘08 2t, the screws maybe are meant that long for a plastic base choke?

I watched a video about "unsealing" the carb (90gtvert?), so I'll tackle that.

Two methods come to mind for screw removal. Use a tool to cut a straight groove in the screwhead, allowing usage of a flat blade screwdriver. Second is a left-hand screw removal tool which drills a hole and engages tapered threads which should jam into the fastener and loosen it up foe removal. A 5-6 piece kit with case available on River or Bay. "damaged screw removal tool" seems to be a good search term. If not too aged and corroded, screw removal is not too difficult. The pilot jet(and main jet) is removed from the bottom. You only need to remove the diaphragm cover(top) if you want to mess with the needle settings. You need a JIS style Philips to have good bit fitting. A pliers or Vise-Grip may grab the side of the screw and make loosening easier. tom

I didn't bother to drill out the screws. I just went ahead and bought a new 20mm carb, from Scooters To Go. It pairs well with the 72cc kit. Runs pretty well, now. Just need to adjust the valves better. I thought I had them dialed in, but they're kinda noisy.
