| 425.1 | leaning out | SICVAX::SCHEIBEL | U can Teach A new dog UL TRIX | Thu Jun 29 1989 11:01 | 7 |
| sounds like a dirty fuel filter, bad fuel pump, broken vacuum line off
of manifold or clogged high speed orifice plugs. If you choke it and it
runs ok that usually means you are leaning out the lack of air/extra
gas makes the motor pick up speed. Let me know how you make out.

| Might want to check for a stuck choke also.
Good luck,

| Some of the older Johnsons have a psuedo-automatic choke that
stays ON when it dies. All you have to do is use the manual
override button on the front of the engine itself. I think
you pull it out to start and then push it in to run, or vise
versa. It sounds like you've kinda discovered it already.
Also it should stay in by itself.

| 425.4 | plugged someplace or an air leak | BIZNIS::CADMUS | | Fri Jun 30 1989 10:10 | 27 |

I've had a similar problem twice in the past- the rubber fuel line
starts to distintegrate and little pieces get into the feul opening in
the carb.enough fuel gets by to run at slow speed, but not enough at
high speed.
I'd check the choke, clean all fileters, and check the carb for
dirt/junk around the inlet.
It's definetly starving for fuel and is probably a blockage.
I also ran into this last year with a freind's baot with a 125 FORCE
the (*^&&*&$@#*&^ dealer had a real slipshod connection between the
rubber fuel hose to the engine and the copper line from the tank-
under full load, enough air would blled through, that the fuel pump
could pump only slightly less than the engine required.
The engine would pick up , go to full rpm and stay there for about
10 min and then sslllooowwwlllyy slow down to about 2000 rpm. Once the
fittings were hooked up proper and leak free- no problem.
I would look for plugged line or a leak in one of the lines on the
suction side of the fuel pump.

| 425.5 | Check the "O" rings | ALLVAX::ONEILL | | Fri Jun 30 1989 13:08 | 8 |
|
Check the ends of the fuel lines. Many of the connectors use
"O" rings. If the "O" ring gets wore it will allow air to get into
the system.
Good Luck

| 425.6 | Shorten fuel line? | WFOV12::KULIG | | Tue Jul 18 1989 07:38 | 9 |
| re .0
I had the same problem, tried everything in rep .1, changed fuel
lines, cleaned carb, cleaned fuel filter. The problem turned out
to be the length of the fuel line from the fuel tank to the motor,
it was too long for the fuel to get to the motor. I shortened it
by about 2 1/2 feet. Runs great now.

| 425.7 | What note? | SALEM::GILMAN | | Mon Jun 10 1991 14:44 | 5 |
| I have done a dir/title for a recently added to note about 'scary
scenes' or something similiar to that title. It was about spooky
things people saw on dives. I can't remember the title well enough for
dir/title to be able to id. it. Does anybody know what the note number
is? Tx. Jeff
