[Healeys] Bad running due to ethanol in gas?

[Steve B. Gerow]

Alan,
Thank you for the suggestions - will keep them in mind as I move forward. 

The car doesn't come close to failing - it just occasionally runs wierdly under certain specific circumstances. 

BTW - today I filled it with Arco Premium (vs Unocal regular), which tested at 5% alcohol.

Will report back to the list if it runs better with the Premium gas.
