Never worked on this particular model, i removed the nuts holding the carb on, but it appears i need a star socket (6) socket to remove the studs so i can take off the carb?
Is that correct?
Thanks.

back on this engine, got it running, runs great and smooth, however, even when warmed up will only start on choke, and the muffler is glowing red, and i've always heard this is caused by the fuel mix too lean.
Intake gaskets are oem new. i soaked the carb and sprayed everything out with carb spray and compressed air.

i looked back at the parts diagram, i realized i had put the intake gaskets in the wrong order, redid those, thought maybe that might have something to do with it (?) but it didn't change anything.
after about 1 minute running, it starts glowing.

Firstly check the plugs
If the plugs are a good colour don't worry about the exhausts
A lot now days run at red heat in order to completely burn any fuel that gets to the muffler via valve overlap for example.
If the plugs look like it is burning too lean and the carb is clean then take to the main jet with one of those tip cleaners & enlarge the jet a touch.

It's got a brand new RC12YC plug like was in it, the old plug looked fine, greyish tan color. slightly dark. I may try the old plug in it too, just to see. I'll take the new plug out and see what it looks like now

Okay, took the carb off, cleaned it again real good. Fired it up, ran it for 10 minutes and the muffler, woops, Muffkin, didn't glow at all.

That looks too lean to me .
check it with a few more hours on it .
If it is a customers mower then put a service note that the engine seems to be running lean as per the Cal EPA regulations & needs to be inspected again in Y months.
If it then blows up your bum is covered
In my shop, the jets would have had a kiss from a tip cleaner ( file ) to open them up a touch.

Your smallest jet in the carb is blocked. The small jet is used with starting, idle, and acceleration. When scuzz starts forming inside the fuel system, it's the smallest jet that ALWAYS gets blocked first.

It will never get unblocked by itself because the vacuum inside the carb isn't enough to do anything except lift fuel a few MM. Fuel conditioners and cleaners (like StarTron) will really help once you can see light through the jet, but the cleaners must be flowing through the jet in order to clean.
