I like these old V4 engines... looks good on my 1964 16-1/2' whaler Katama. But mine sputters at idle and low speed.... runs rough. She smokes (could be my oil/gas ratio) yet at WOT she the sputter goes away (of course). Bottom line is she just doesn't leave me confident to allow my youngest daughter to take her out for a day on the water.
In my area (Northeast, Boston) for some reason mechanics don't like to work on the older models. One place told me that the carbs are worn and need to be replaced. He did a link/sync and turned up the idle. Runs a little better but I am just not happy..
Snapper in Australia had a similar issue. His engine is now running like this --> Smooth Running V4
DAMN! If I could have mine run like this I would be ecstatic! When she first starts it sounds like she is not running on all 4 cylinders. After I giver her a fast rev she blows by her stumble and will idle. Eventually she begins to sputter. I've looked through the sputter threads. I found one by Snapper Fisho who got to the bottom of his issue. Hopefully I can get there too!!
I've:
What next? Timing with a light? Inspect the carbs again? Thoughts????
Thanks!!

I've:
- replaced the thermostats
- cleaned out the water cavities (all the sand over the years)
- new head gaskets
- new plugs
- new wires
- new carb kits
- new water pump
- I can post compression for each cylinder.
