Introduction and Ask

[RobbyBobby]

Hello, my name is Robert and I am A Owner...

I would like to ask for your help.

I am new to Atomic Four. Become owner of one by very recent inheritance of 1977 Catalina 30.

This engine was working fine for first 3 nm, or 45 min. Next just stopped. No warning signs, no overheating. Just stopped. I got towing service and spent the rest on my journey relaxed. of course I want to fix it. No experience with gas engines, moderate with diesels. Here is what I am getting when attempting to start the engine. Video link

PS. I am dedicated to learning about my new power house, already purchased the Service and Overhaul Manual and.... decommissioned engine
