Xr80 that wont start

Hi, I have a 1982 xr80. When I got it, it hadn't run in at least 4 years. I soaked it with Marvel Mystery oil. It needed a cylinder head because the spark plug hole was toast. I got a used head and put it on with the same cam and cradle. I checked the deck, made sure it was level. I reassembled the bike and got it running. For a small bike It had some nut. I road it for about 3 hours till dark. I started and stopped it quite a few times. I parked the bike under a tarp for 2 days while it rained. Now I can't get the bike to restart. I have good spark. I tried to pop start it going down hill and it sounded like a small block Chevy trying to start while being out of gas. So it had compresion. But felt like it was out of gas.I took the carb off and cleaned it out again. I did find some sediment in it.I drained the tank ond cleaned it out. I put it back together again with a fuel filter in line this time. I got fresh gas and I still can't get it to start. Should I just replace the carb or am I missing something. This seems like a very simple design. I do have the Haynes Manuel and I feel I've gone threw it pretty good. This is my first bike but I've been working with cars for 15 years. Please help

I found the problem. The spring clip for the throttle valve allowed the e clip that holds the throttle valve in place to pop up and allowed the carb to flood out. It also fouled the spark plug.
