running on 5_not any more

Hi All,

On a beautiful sunny day last week I fired up to meet a friend for lunch. My Pagoda informed me that - -  NO we are not leaving the driveway.

Of course, the first thing I did when I got the time was pull the plugs. The #1 plug had an obvious sheen to it and smelled of raw fuel. Having had prior experience
with fouled injectors on this engine, I pulled the #1.

After smacking it down on the workbench four or five times, you can plainly see the grit that was dislodged. Mystery solved.

Last year I installed a new Metric Motors engine. During the 6 months or so the injection pipes were open to the atmosphere, I neglected to fill them with preservative oil
like I knew I should. Oh well - -  lesson learned.

Hope this helps one of you someday.

How the hell did that get in there?!

all I can figure is that if they will rust on the outside they will also rust on the inside - - -

It may be just debrie/dirt entered one tube and not a flake of rust.  The tube ends are normally pointing down.  I've stored mine for a short time opennings  down but I blew them out with air to make sure I didn't drown any spiders or earwigs on restart.  There is an integral filter at the inlet side of the injectors if I remember correctly.  So you should be good shape to inspect and clean the inlet.  I would run a medium gauge copper wire (like telephone 18 to 22 guage) down the pipes pulling a cloth sprip with gun cleaning oil through each tube.  If no rust on the cloth, no worries.  I think the outside of the tubes are in a plating-harsh environment and exposed to rubbing and wellmeaning attemps at cleaning.  That is why they tend to loose the plating.
