Cold start questions

I have a 88 yj with a MC2150. It's runs great most of the time but now that it's starting to get cold out it runs a little rough. It's starts good in the morning but in the afternoon around 7ish, it has some issues. It will turn over but has trouble starting. Once it does start, it usually stalls even with me keeping my foot on the gas to get the rpms up. After a couple try's it'll eventually start up and I'll let it warm up for about 10 minutes. After that it'll still stall if I come to a complete stop for a couple seconds. If I need to, I just shift to neutral and keep the rpms up until the light is green. Any suggestions on cold starting or warming it up?

Okay I'll check it. When I tried to start it up today it would not fire up for a while. Mate 10 minutes. I hear what sounds to be grinding of gears. The starter is only a couple months old so I'm guessing it's the flywheel. It's getting worse and worse and I'm leaning towards the flywheel. Anybody know if this is it? I also heard that the flywheel is a pita to replace. Is this true?

Pull the starter and turn the engine by hand. Inspect ring gear teeth on flywheel for damage. If damage is found, you need to replace the ring gear and starter bendix, standard maintenance work.

On your carb, get the workshop manual for that carb and set the auto choke to spec.

Okay. If the flywheel needs replacing, is it a pain to do?
