Hi,
I have an Atomic 4 Gas Inboard on a 1978 Catalina 27. It is still sea water cooled. Whenever I pull the throttle lever all the way back to idle, the engine dies. This just started randomly after running at idle just fine for over a year when I first got the boat.
I have done the following to try to fix it:
1. Cleaned the carb and air intake filter
2. Oil change
3. Replaced the primer hand pump (positioned vertically correctly)
4. Replaced the fuel filter
5. Replaced the spark plugs (I know this wouldn't help for the problem, but did it since I was working on the engine anyways)
The engine runs and sounds brilliant so long as the throttle lever is slightly forward giving the engine a bit of juice.
Any thoughts on how I can fix this or troubleshoot would be much appreciated!
