Overheating Atomic 4 - Page 2

One head gasket. I have owned many flat head engines, and absolutely swear by a single head gasket.
I have been able to crank over an A4 and a Volvo MD20 (I think that is right). It is great if you have no electrics in the boat, or if there is a battery problem. The Volvo never ran right, and I removed it, but it did start once. The A4 was a piece of cake.

Has anyone ever been able to start the engine with the hand crank? The whole idea just seems silly to me.

Yes when I was a kid back in 1972 I would start my fathers Atomic 4 by hand cranking it. He had an Irwin 28. When it fires up you got to get that hand crank off quick.

One Headgasket or two?

The answer is simple the old headkaskets are not available any more. When you order the headgaskets from Moyer Marine Atomic 4 Engine Rebuilding and Parts they will send you two. Don't make the mistake that you think that they sent you an extra one. Use both.

As far as the "dangers" of gasoline.

This was a popular ploy of a certain Diesel Engine Maker....that bought out Universal.

Kind of like the way General Motors bought up electric trolley companies and replaced them with buses.

In all my years, the common denominator for Gasoline Fires has been poor refueling practice, using a drill pump to evacuate gasoline from a tank (seen twice in Baltimore)
or just poor maintenance of fuel system.

IMHO anyone that goes down to a boat and "fires it up" like a car w/o checking is axeing for trouble
