Thanks so much for the guidance everyone!
Stephen – I will definitely have a look at the reeds. It's something I've seen talked about but was hoping to avoid removing the intake. Oh well.
Pat – I will try to spray some premix into the plug hole. May just need that level of help to turn over again since it's been a while. But the petcock is new and the bowl is filling with fuel.
Aaron – Do you have a link with more info on this or additional guidance on jet size? I didn't realize I would need to do some set up work on the new carb. It does have a jet already installed in the bowl – but could obviously replace it if that's your suggestion since sizing is dependent on the bike.
Thanks so much everyone! (edited)
