Car won't idle.... again

Had that happen to me a couple of times with a bad batch of gas. I bought gas at this local place cuz it was so much cheaper, two times, on widely separated occasions.The second time I was a bit smarter; I only put a few liters in and drove it around the block. Well I knew instantly that their gas was not going to work for my tune. I went back to my usual watering hole, and let her drink the good stuff.Problem solved. Since that day I have purchased gas almost exclusively from the same place, for around 10 or 12 years now, with never more an issue.

In 2004, my son and I went to CarCraft Nationals in Shakopee Minnesota. Well this is an 11 hour ride at the speedlimit,and thus more than a tankful. I had taken about 40 liters of,back-home, good gas along in approved containers, for which the border crossing guys wrinkled their eyebrows at. Well I knew that those total of about 100 liters/26 gallons US, couldnt get me there and back. So I gassed up in one of the Dakotas, somewhere on the way down, and within a mile I could feel the car doing strange things. I pulled over and pushed the clutch in. Engine died . Well I connected the dots pretty quick. Having had the for-thought to not leave home without my Holley tuning kit, and basic tools, I swapped bigger Mjets into the primary side and cranked out the idle screws, and dialed in some extra cruise timing, and down the road We went. A mile later, I was again swapping jets. My 20 year old son was impressed. He thought we were done. But,Badaboom. Back in action. IIRC i went up 4 sizes, to get going.
I went back and asked the attendant what he had put in my tank.I remember it was oxygenated gas,and a higher ratio than back home, but I dont recall the ratio.He mentioned a place a couple of blocks further down the road where I could purchase non-oxygenated gas, premium only for "farm use". I filed that info in the back of my mind.After that I was real careful to ask.Eventually,we burned up that tankful,and the carb was returned to normal. I still had the stash in the trunk, from which to draw if I needed to.But in Minnesota, at that time, I seem to remember their gas was non-oxygenated.
The rest of the trip was uneventful, as to fuel issues, as we left Minnesota with a full tank of their good stuff, and returned to the town in Dakota, where we knew we could get the premium.
Those were fun times. Me and my boy,together, blasting down the road.
Oh, and the show? Yeah that was a good time too. It was huge. I think we spent two full days checking it out and cruising around in the evenings til we couldnt stay awake.
Yeah, fun times.
