Nice effort on keeping the ole' girl alive.

All the Caprice/Playboy's used the 2-stroke V4 90, derived from the
outboard powerhead. From the sounds of it you've done a lot of
electrical/ignition system work, so my money is on a fuel-related issue.
It's fundamentally either spark or fuel.

I'd recommend pulling the fuel tank and doing a full cleaning/sealing
and then I'd recommend you install a fuel/water separator filter. Once
everything is clean then I'd double check the fuel pressure/pump. It's
doesn't take much (fine rust particles, etc.) to cause a lot of grief in
the fuel system or erratic pressure to cause float bowl or ether issues
in the carbs. This is especially common in boats that sit idle for a
long time.

Sounds like a nice boat, don't get too discouraged, your probably very
close to getting her dialed in.

Subject: [OMC-Boats] 1966 Johnson Caprice

Hi everyone!
I so enjoy reading all of the entries and learning more and more about
these wonderful Ol' Evinrudes and Johnsons.

We have a 1966 Johnson Caprice.
We have owned it for 3 yrs.
Last summer 2007 we got it running for 1st time in 10 years.
* carb was rebuilt (thanks to parts from Sea-Way in Seattle)
* new coil as old one shot keeping ignition turned on (learned that on
* all new lead assembly and Spark plug terminal assy.
* new distributor cap and lead assy to coil
* replaced points and condensor.
* rewired under dash and installed a horn.
* new ignition installed.
* new CD/radio and speakers installed. (we don't use it)
* steering works well.
* tilt motor works well (sometimes I have to toggle the switch a bit)
* timing was adjusted on testdrive
We took it out 3 different weekends and each time she started right up
and ran nicely. Each time for 2 hours aprox.
At the end of last summer (labor day) we noticed it would run fine for
about one hour and then at full throttle it started missing and slowly
wanted to quit. It would start and It would throttle up fine for about a
minute and want to quit.
No time to get it in to the shop so I winterized it.
* This spring we got her in to the shop and have cleaned the carb again
and she runs fine
  for about 1 hour and then wants to quit at full speed or mid speed.
Any suggestions??? Thanks. This is a great website. Bob & Barb
