I have a 25HP 1996 Mariner (model 25ELH) and also a 15HP 1992 Johnson
(model J15RENM).

The Mariner is an electric start, the Johnson is a pull rope start.
Both are 2 cycle engines, mixing the oil with the gas (50:1).

Both motors have set for 2 years without running. Before that, they
were both running sweet. Now, I have to run the Mariner at full choke
(runs sweet at that setting), and the Johnson at half choke (that one
stalls a lot even at that setting, but one pull starts it again every
time).

I'm assuming that the old oil/gas mixture has something plugged. I'm
running SeaFoam through them both (mixed in the gas), but have just
started that process so I haven't any feeling on how that will help
yet. I am thinking I may need to chemically clean the fuel filters
and possibly run wires through the carb jets to clean them out.


I'm looking for a copy from a manual on each of these motors showing
the location of the fuel filter, and also the carburetor jets. If
anyone happens to have a service manual on either or both of these
motors, I'd sure appreciate it if you could run a scan of the pages
showing these and send them to the above email address.
