[Mgs] Petrol

Ethanol makes big Agra happy= more political donations.
My back g Healey was built in 1976. Have replaced my hoses and rebuilt my
carbs twice.
I just had all fuel hoses replaced and top of carbs rebuilt before refiring
the engine on my 67B
I give my Healey low lead Aviation gas every so often, but try to run
ethanol free high test. Will do the same with the B .

I don't drive either one enough to burn the valve seats.
Happy motoring.
Our driver  season is nearing its end. I hope the B will extend it with
roll up windows.
