Pulled the air filter to see what I could see, turned engine over again and see fuel spurting out of the fuel bowl vent.
My question is this, is this a simple pull the carb and clean it out issue since it had bad gas in it as well? If so, am I going to have to get it re-tuned once disassembled or is it easier than that?
2nd question, I never had any of the vacuum ports connected to my dizzy, is this an issue or do most of you run it this way?
3rd question, all gas stations around here sell 10% ethanol fuel, but I did find 1 station that has pure gas, 91 octane only though. Is 91 octane ok or will I have to adjust the timing? I was previously running 87 octane.
Thanks in advance

Welcome (back) to the club!
1st question: Probably your float needle is gummed up. I'd tear it apart and look about rebuilding the carb. It's an easy job and you probably need to do it anyway. You can get USA made rebuild kits from daytonaparts.com or you can get a kit from Autozone and just clean and re-use your float needle. The chinese ones in the kits now dont close properly (badly tapered).
As far as re-tuning as long as you don't bend any linkage or monkey with the screws on the front of the carb you should be OK to fire it up and go.
2nt question: all of my vacuum ports are connected so the timing advance stays working. Maybe you have HEI? IDK about that one. Someone else will have to help there.
3rd question: Octane is how the keep the gas from causing engine clattering. It wont affect your truck one way or another. Its mainly for the newer cars that have to have real high compression. We could probably run 50 octane and be fine
