Starts up fine but idle is like it needs a tuneup, floods out and pops when I give it gas.

Hello and welcome to the site

It sounds like you have low compression or a blown head gasket.

Here are a couple of guides to get us started in the right direction.

If you need a gauge you can rent one for free from the auto part store.

Please run some tests and get back to us we are interested to see what it is.

Cheers, Ken
