Those small EPA approved carbs are about impossible to clean. I would
suggest getting a new carb and if you don't use a ton of dinghy gas, buy
ethanol free gas from somewhere. I fill a gas can with 100 octane from
the airport for my lawnmower and have no issues at all with it :)
Failing that, put SeaFoam in the gas.
I would NOT get a Chinese knockoff engine. Craigslist will sooner or
later come up with a little 2 or 3 HP two-stroke you can pick up with 2
fingers.

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
