The automatic choke on my Toro personal pace lawnmower is wide open at initial start. Nothing appears to be gummed up as all the linkage moves without issue. The only way I can get it to start is to reach in with a screwdriver and close butterfly disc while someone else pulls cord. Any suggestions??
Thanks,
Jim

is yours a briggs and stratton flathead engine?
<span style="font-family: 'Verdana'">Get me the engine numbers and I'll figure it out for you. If you can't get me the engine numbers, get me the model and serial numbers off the mower.</span>
Does your Toro have a Kohler engine on it? If so, watch this video and do what it says:
I have an Airens with Kohler Courage and had choke issues. I found dried grass covering the linkage that was hard to spot until I took everything off covering the carb.
I will post the engine numbers when I pull them later today. Sorry, that's info I should have had already. When I had it apart I didn't notice any linkage towards the muffler only linkage that kept it open without resistance. The linkage in place moved easily from open to close but its normal position was open.

based on your model, you may have a thermostatic choke opener on your exhaust muffler side:

part # 291
That is not closing the choke plate properly.
Part #: A-291 593208

You got 15 years of good service out of the auto choke. I'd be inclined to just fix the autochoke and get another 15 years out of it. The part you need to change (Briggs 593208 thermostat) bolts behind the muffler and is easy to change.
The other version of that engine usually doesnt have a choke. It just has a simple primer bulb which enriches the start up and sorta acts like a choke. You can change the carb to the primer version (Briggs part 799868) and you will also need the aircleaner base for primer engines (part 795259) or add the primer (Briggs 694395) to your current base.

Replace it. The part number is 790830. The thermostat is supposed to keep the choke closed when the engine is cold. But keep in mind though the thermostat is about the same price as a new carburetor with a manual choke.

I guess I just assumed it was an automatic choke but it very well can be the primer bulb version. I have both parts you mentioned in the primer scenario. They just appear to be very simple parts that I didn't think they could fail.
Is the spring that keeps the choke closed when the heat riser isn't holding it open missing? Remove the plastic top and take a digital picture of what's there and we can tell you.
