Dave, I never failed to give info on the A4, and I've done it more
than once. The A4 had water in it and we pulled the head and freed up
the valves.

Happened to mine, water muffler filled with scale over the years and
caused the volume to decrease. When shutting down the engine, there
needs to be enough room in the muffler to take the water that is over
center in the anti siphon loop. if not drains back the wrong way
seeping into the rear cylinder through the exhaust valve. took us a
long time to figure this out, it is not something that you would
normally consider as a cause.




I pulled a carb from another A4 which was in better shape

had to replace mine, after cleaning it a dozen or so times, found out
that the metal in the carb bowl was corroding and gumming up the main
jet. no amount of cleaning would give more than temporary relief.

found out you can buy that carb at any industrial supply house for a
lot less than a marine source.

and then got the motor running off the boat. Probably the toughest
part was getting the motor back in correct alignment.
As for the other questions...what's the point? I could look up
anything I don't know and I never professed to be an expert, only a
fan. I rarely bother with such questions as folks like Bob Crantz and
Doug are google-maniacs anyway.
I know cheap trailer trash and Doug fits that to a tee. His
explanation of why he doesn't watch films is all I need to hear.
Scotty, if possible, is an even lower form of life.
Gotta run now. I'm making some safety lines in my shop for a short
trip we're doing with Thomas in July for a raft-up in Port Jeff.
