Greg,
Sounds like you are on the right track, however, do not expect the engine to idle perfectly after a start in cold conditions. It takes some warming up before a good idle will start. No chokes used on the 356 carbs. Even in warmer weather, the engine probably needs a minute or two of throttle before it' finds itself'. Simply the nature of an engine designed basically in the nineteen thirties.

I love this idea... anyone have a downside to this option?
Tim Berardelli, who runs a shop and posts here, did some research; those are not designed for use in a hot environment. I'll contact him to give us the info.

According to Attwood Marine, the folks who make an EPA approved marine primer bulb the operating temperature range for their product is 18-122 degrees F. How hot does your engine compartment get? Like the guy says on the radio-"just a thought, not a sermon"
