I have an old Johnson 3.3 ( 1995 made in Japan ) and the only issue I've had
with it was the main jet getting clogged ( very small jet, blocks easily ),
Once I started puttinf Fule stabilizer in the gaz the problem went away ( took
as little à 3-4 weeks without use to get clogged ).
An easy test to know if it is the fuel supply, you can make sure the plug is
clean, then squirt about half a teaspoon of mixed gas in the engine, if it
starts and run for a few seconds then investigate the fuel supply.
I used same test for my A4 a few times ( pour a little gas through 2 or 3 of
the spark plus holes, plugs back and start it.

I rebuilt the carburetor of my Suzuki 2.5 engine last winter and it seemed
fine for a few runs and then quit completely the other day and won’t start. I
have read stories of people cleaning the carburetor 5-6 times before they got
these working again when there are problems. I probably should have put in a
fuel filter as some posters recommend, but did not. Anyway, I am considering
replacing the carburetor, buying a new engine or both. It is a long row, and
while good exercise, I would not want to do it against wind and tide. Although
cheap and plastic, the Suzuki is the lightest on the market (30 lb) and while I
have had some problems, it has lasted nearly 10 years and been pretty reliable.
Arguing for fixing or replacing with same is that I now know the engine really
well, so can probably keep the next one in better shape for longer. What
trashed this one was a water pump issue I did not notice that overheated the
engine and probably warped the cylinder 5 years ago. The only engine close in
terms of weight are the Honda and the Yamaha. The Honda is really noisy and
really got trashed in reviews as not reliable. Some people hate the
centrifugal clutch as well. I can find nothing about the Yamaha in terms of
people’s experience with it and it is hard to find for sale. It is about 6
pounds heavier than the Suzuki, but at least it is not 10-12 pounds heavier as
most (Tohatsu, etc.) are.Then I came across a bunch of small engines on Amazon
that I assume are Chinese imports. They are only about 20 pounds (vs. 30 for
the Suzuki) and less than half the price. I have never seen one on a boat in
my area.Any advice from the group? Thanks- Dave
