Thinking back to the first "gas crisis", I rolled into the local Sunoco station in 1972, out of gas. I brought a pail of gas to the car and started it right up. I can't say bubbles are not an issue, but in the 50K miles I owned that bird, I never had bubbles stop me in my tracks. I don't see running out of fuel, bubbles or hearburn & indigestion causing starting issues for more than a moment or two.

My 82 truck weaps fuel though the carburetor. The only consequence is I need historic tags (emissions failure) and it takes longer to start after it's set a spell.
