Re: hard starting 440

[Jimmy Peavy <peaver63@xxxxxxxxx>]

If all you need is a brief push from the car sitting for some time,
then you only need to turn the electric pump on to fill the carb
bowls, then, turn it off.
I really don't think busting a diaphragm with an electric pump is on a
brief usage at start up, is much of a possibility.
Get online and goggle it. "Anybody ever ruined a motor by busting a
diaphragm in a mechanical pump?"
Here's one such topic.
