Same findings here, no additive as of yet that I have been able to find! One other problem I have encountered is they are more susceptible to vapor lock with todays gas also. The only thing I have found is an electric fuel pump for starting purposes if the cranking is an issue. I just crank mine over a few times, then pump the accelerator 3 or 4 times and they start.

It always goes eventually but takes 20 or 30 seconds of cranking. A little research (see link below) suggests that modern gas evaporates quickly and the carburetor bowl evaporates through the bowl vent. They suggest priming the bowl through the vent with an eye dropper. Does this make sense? Is there any kind of gas additive that would help prevent evaporation? http://www.thecarburetorshop.com/Troubleshooting.htm As always, thanks. - Jim Jim Altemose, Long Island, NY '63 Polara 500 (Max Wedge) '63 Polara 500 (383) '65 Belvedere I (Street Wedge) '71 Bronco ---- Please address private mail -- mail of interest to only one person -- directly to that person.
