Lots of cranking and pumping to, I think, refill the float bowls. Is this due to the garbage ethanol enriched fuel we are getting at the pumps these days?? Does this gas evaporate that fast? If I start the car every 4 or 5 days , its fine. Just curious if anyone else is experiencing this problem with pump gas? If so, any solutions?? thanks

Just curious if anyone else is experiencing this problem with pump gas? If so, any solutions?? Its a very common problem so more than likely the answer is yes, it's todays fuel. Fix? Electric fuel pump will usually reduce the start up time to a minimum. Not the best choice if trying to keep everything 100% stock but it works.

I take the air cleaner off and use a small bottle of fuel to pour a bit into the carb vent tubes. I don't want the non-stock look of an electric fuel pump. Sheldon

It's especially common with winter grade fuel in the spring/summer. If my D100 sits for more than a week I dump a tiny bit of gas down the carb throat, it's usually enough for it to stay running until the float bowl fills up.
